Caporegime
Well gents I'm back, having yet more problems at home only this time she may have gone too far....
Tomorrow is my birthday, 29th and she knows how important birthdays are to me especially since my Dad died and I'm estranged from my mother, we don't have a lot of money but I had budgeted enough for a semi nice pair of shoes I'm in dire need of for my birthday, however as of today she has apparently gone out with her friend and bought herself a top and had a rubbish meal at some greasy spoon type of place.... She told me tonight not to get so worked up over it, it's just a birthday and its nothing special and then promptly took herself off to bed without so much as a good night!
I hope that it is just some tasteless joke because if she is being serious well that's it for me and her and she can go whistle, I'll go into a hostel if I have too and keep up my studies and be that good role model for my kids, funny thing is yes I will suffer in the short term but hey if I leave then that's her having to drop out of university yet again and a life on the dole awaits as she can't do her degree without my support, I don't mean that in a horrible way I mean she literally has me write her assignments for her and then not to mention that as we live so far away from the university there is no way she can drop the kids off every morning or pick them up in the evening without being late every day and having to finish early something the NHS wont stand for.....
Personally I don't get her logic, if I was so dependent on someone else and my future was riding on getting their help even if I didn't want to be with them any more I would at least try to keep things civil!
Threatening to leave is an empty threat if you never actually leave. I'm not suggesting you do (although I would, I think) but your wife sounds like a terrible person who is quite content to carry on with her behaviour because there is no reason not to. You've said you'd leave before, she became contrite, you didn't leave, the cycle continues.
Two things you could do some reading on : co-dependant relationships and passive-aggressive relationships.
