NCd for this one. Broke up with my fiancé a couple of weeks ago, after a few arguments and he decided that it was either my career or him. I picked my career, and he seemed a bit shocked by this. Ever since, he gets in contact every day with a new issue.
First, it was wanting to check I’m alright. I tried to ignore, them he started to call and I messaged him saying “I’m fine, we don’t need to talk about this anymore.” He continued, and asked if I ever really thought we would have worked with my job. I ignored, and he responded again with “sorry I don’t know why I’m doing this.”
He then asked for gifts I’d bought him to be sent to him directly, and I didn’t reply. He then said I’d probably want the money and I’m easily bought. He finished off by saying he’d pay me for the time I had spent with him the last few years. It made me feel like he sees me as cheap, whereas this is a man I loved and wanted, at some point, to spend my life with.
Then it was wanting to arrange our personal items between us. He was reassuring me he will take care of the costs etc, and tried to pressure me into taking things before I move (moving to a new country for work) and then move them myself. The items are in OUR apartment, not just his space.
Now, he’s got a bacterial infection on his prostate and messaged me saying that it was probably because I bled the last time we had sex (common for me, as I’m quite small 
). He said my blood is dirty and carries bacteria, and I need to go get checked. I’m 99% sure this is rubbish, but have booked a gynecologist appointment and done an STI test just in case. I have always regularly done tests, part of a health check we do quarterly at work. He reminded me not to have sexual contact with anyone. A year ago I had a miscarriage due to being unknowingly sensitized Rhesus negative. I went to therapy because I felt guilt that I’d hurt our baby, but he seemed supportive at the time. So now to be told my blood is dirty seems particularly painful.
The thing is, I always thought he was quite a nice guy. Everyone likes him. I loved him. Now I feel incredibly hurt, and like I can’t trust my judgement of people, something I’ve always felt quite good at. AIBU to think that I should’ve known he wasn’t the nicest? Or is that just hindsight? I can’t block him as we have to arrange to de tangle our lives, but I wanted to do that with a modicum of dignity. How can I prevent me falling for this type of person again?
