Well in light of the new information I wish you all the best and hope you can get through this as quick as possible, I can only imagine what your going through right now, you'd probably give your arm away if you thought it would make you feel better, I know it's an old and probably overused cliché but time is a healer, it won't be easy, you just have to wait it out, keep in contact with your close friends at a time like this, they will offer you the best advice and support you, I know at times like this people can often make some very irrational choices without really being aware of it, probably the best thing you can do right now is box everything up and store it away for now until you get your head straight, games consoles don't ruin relationships, peoples actions do.
Obviously I don't know the finite details of what is going on atm but if there is a chance you think you can 'fix' what has gone wrong then try your best to do that, but know where to draw the line and move on, also remember when things go wrong no matter how bad you feel at the time, usually it happens for a reason, good can come out of it, be it building up your character, be it a learning experience that makes you wiser, or simply it was something that wasn't ultimately meant to be, I'm not sure of your mental state of mind atm but if your finding things really hard don't worry, you'll get through this, take care.
