I'm glad you asked for advice before making any rash decisions.
This sort of situation can go wrong way too quickly, and I wouldn't want you to find out a year or two down the track that you'd gone the wrong way. Now, this is indeed a major issue, but I urge you to think it over very carefully before comitting yourself to a course of action. My honest advice would be to seek professional help and save yourself future heartache, but if you insist on doing something about it yourself, then I must say that you will have only yourself to blame if it goes pear-shaped.
BTW, this girlfriend of yours . . . what's her mobile number? She sounds like a goer
