I'm here because a friend directed me and just thought I'd give you a female perspective having been in a similar situation. Twice.
What's coming across loud and clear to me from your reaction is a sense of grief and loss over the baby and the relationship.
Someone above has given you a link to BPAS counselling. I'd give them a miss. When I had an abortion their counselling wasn't independent - they advised me that an abortion was my only option. They weren't interested in helping me with dealing with the emotional aftermath either. I guess it makes sense because BPAS make money from providing abortions; if your girlfriend has one on the NHS, then they will bill them for it. The NHS contracts out most of their abortion services to private providers.
When I fell pregnant a second time unexpectedly (and yes I know how contraception works, thanks) my experience of abortion meant that I simply couldn't face it again even though my husband was threatening to walk out on me if I didn't.
There is so much I could say, but what will suffice is this. My husband was adamant he didn't want a child - he spent the entire pregnancy in a state of depression while I was wracked with guilt. Our child is 11 and is the best thing that could ever have happened to us.
I think you BOTH need to remember that a pregnancy, even when it is planned (I went on to have more children) is scary and daunting. I don't want to join in the hatefest towards your girlfriend although I think she is sounding rather irrational and unreasonable, because I know what pregnancy hormones, especially early pregnancy hormones do to your brain. I go completely crazy when I'm pregnant. She'll likely be feeling like **** and incredibly defensive and vulnerable. She obviously wanted the baby too, which is why she seized on your positive feelings as affirmation.
Because she is vulnerable after previous relationship experience, she is obviously looking to tie you down into her Tcs & Cs because she is insecure. She wants to know that everything will be just perfect for the baby. That's understandable, but she needs to know that as a mother, having an abortion will hit her that much harder. She'll know precisely what it is she is losing.
Both of you need not to sweat the small stuff. I can see that the desk thing is important, I also get the devotion to your animals, but without sounding harsh, if you've had some of them since you're ten, they may not last much longer. Maybe you can come to some compromise, whereby you agree not to replace them when they're gone, but bring them with you anyway.
I think you have to tell her that you love her, you want to have the baby with her, but that she must understand that relationships are a series of compromises, that you have to work together. You both have to listen and be prepared to budge a bit of ground, although I think probably your own desk is a non-negotiable. But for heavens sakes? She's going to abort your baby because you'd like your own desk to work at and to sort out your career? That's not rational or reasonable and she needs someone to help her to understand that. There needs to be give and take. But then again do you also want to look back and think that you chose a cat/dog/hamster and your own personal working space over your son or daughter? I don't think that you would necessarily resent her or the situation in the end, but as I said, there needs to be compromise.
I do get that this is terrifying, going from being single into a full-on relationship with a child in a short space of time always is, but it does work for many people. You sometimes have to take a leap of faith. We're all encouraged to be so self-orientated these days.
In terms of the exams, as others have said, these can be flexible. Look, a newborn baby pretty much sleeps all day for the first 4 weeks and spends the majority of time only wanting its mother. Your job will be to make cups of tea, sympathetic noises etc. The 4 year old will be at school, so maybe help out on the school run, but newborns really aren't all that much trouble. They're pretty portable too. Her daughter can go to school, you get the girlfriend a nice cup of tea and breakfast, leave her to have a nap with the baby and go and cram a few hours study in. Most men only get 2 weeks paternity leave anyway, my husband didn't get any and I still coped. (I have 5 children, my youngest is 6 months and my husband was away for an entire week when he was 2 weeks old). Does she have other support? Everyone will be rushing to coo over her/baby and to help in any event. You won't suddenly have to do everything and she'll know what she's doing having done it before. It's not half as stressful second time round.
What your girlfriend needs to do is to stop attempting to create the perfect idealised domestic scenario (never going to happen) and instead take a breath and think about the fact that she's got a new life inside her. She needs to have a bit of faith and trust in you and take things a step at a time.
You need to apologise (even if you think you're 100% in the right) for making her feel insecure and if you did anything that made her feel pressured about having an abortion. These days, every single pregnant woman feels under pressure to make the right choice and there's so much cultural pressure out there telling us that the time has to be 'right' to have a child. Conditions must be perfect. It's bull****. When I was 7 weeks pregnant with my third child, my husband lost his job and we lost our house. It was tough, but don't regret for a moment not aborting that pregnancy. Our little girl started school last week. Because you can pretty much get an abortion for any reason these days, it's easy for a woman to feel coerced. I was gutted when my husband proposed abortion and moaned about the fact that men never have any choice in the matter. You have to win her trust and respect.
Please read the rules and fully star out all swearing in future. Thank you.
There's never a right time to have a baby. Sometimes you just to have to make the best out of what you've got and that's the mark of a real man - stepping up to the plate when you need to.
Sorry if that's a lecture, but all the hating on what is probably a very frightened, hormonally challenged and understandably-nuerotic woman (her world has been turned upside down too) was quite uncomfortable to read. I don't think she planned this - some of the most educated people I know have experienced unplanned pregnancies.
You will never regret having a child, but trust me, many many men and women do regret abortion, it's a very painful and traumatic thing.
Good Luck to you both.
