Long term lurker coming out of hiding to garner some opinions as genuinely not sure if IABU or not...
I have recently split up with a boyfriend of four months. Although we had some good times together, I did have a lot of doubts about him. He started and left two jobs during our relationship due to fall-outs with colleagues, he has a long past history of petty crime and drug use (only found that out shortly before our split!) and has some incredibly arrogant views. We also split earlier in our relationship when he told me that he would 'probably cheat on me' (I've no idea why I took him back!) In short he completely lacks empathy. He was also incredibly insecure about his intelligence (or lack of) and would frequently put me and my job (as a doctor) down. By the end, I was only really staying with him as I felt guilty as he had booked a holiday for us for my birthday present. However, a few days before the holiday he got drunk and sent some unprovoked texts telling me how stupid I am compared to him, how worthless I am, how I am a waste of space etc.. At first I thought he was joking but it quickly became apparent that he wasn't. I sent him a text saying that I couldn't continue the relationship. I heard back from him straight away asking for two hundred pounds (my 'share' for the holiday) to be transferred into his account. This was a week ago and I have had several follow up texts. I am genuinely unsure what to do. I do feel guilty for cancelling but firstly, the holiday was my present (so I never owned him a share) and secondly I feel the break up was completely deserved. So AIBU to tell him I am not paying?
