Just over two months ago I was talking to a guy and we exchanged a lot of calls, video calls, and eventually, I agreed to meet up with him whilst I was in his city for work (I'm UK-based and he is USA-based). During that time I had an IUD in which failed as turns out it was not in the right place (now has been removed completely).
During this time the guy I went on the date with and had been speaking to had made a few comments in the past about a girl he knocked up in another state who then 'dealt with the situation' but of which he called her 'the asshole'. He has also been undergoing serious neurological treatments and treatment for potential MS so I felt guilty calling him out on his behaviour. We went to hang out the next day but he was just off with me so I chose to leave early and he ended up reaching out saying he 'needed some alone time' for his health, and blocked me before I could respond. Prior to hooking up we both discussed STI status and my birth control too.
Anyway, I started to get pregnancy symptoms not long after and now have a letter from my doctor confirming an antenatal appointment (NHS), and also three positive pregnancy tests.
He has blocked me on both whatsapp and i-message and does not have social media. I am wondering what to do because I plan on keeping the child (as was told previously due to some surgeries I had a low chance of ever conceiving and am also fortunate enough to have a good support system and the means to raise a child, homeowner etc) and have no interest in having a relationship with him, but considering he has done this before, and because I need to know more about his health issues to make sure they aren't hereditary, I need to talk to him. I have already spoken to a lawyer too about child support and such. My best friend knows about this entire situation and has offered to message him off her phone too and also I've located his mum on social media which he was always saying he was 'close to'. What is the best way to maybe reach him?
