opinions on this situation/ rant

so in July I started chatting online with this guy - he was super nice, we had so much in common, he would listen to all my problems and seemed to really understand them and we just seemed incredibly in tune. He mentioned very early on he was poly and had a long term gf and I was fine with that - I got her insta and we messaged a couple times but were never really close. Anyways he even came to see me in my university city and it seemed like things were going amazingly.

One night after we were flirting I asked if he was free, to which he didnt reply and I facetimed him and he seemed very awkward so it ended quickly and only after did I realise his gf (who he called while she slept - he works nights so he was up late always and she days - was on the phone and we had woken her- to which I had no knowledge at all - I didnt even know they did that). The next day I got a message saying they were sorry to mess me about but they had decided to close off the relationship as it wasn't working out - apparently she had been upset at other things too like how much we were messaging on her Birthday. Anyways I was quite annoyed - probably more unreasonable than I should have been but I felt like we had a great connection and when he was saying how it wasn't fair on her I said -this whole thing hasn't been fair on me either I had no idea she was also on the phone to which he literally responded 'oh yea I guess there's that too'.

Anyways we agreed to be friends and this continued until December (the indecent before was in October) when I get a long message saying he's cutting me off because I was holding October over his head - which I only mentioned a couple times but I do see how I may have been insensitive I guess all this was new to me and I just came out of a dynamic where I had been very badly mistreated and I guess I was extra on guard because I didn't know how to assert boundaries in the proper way and that I didn't seem to care about his mental health enough - which I honestly did not see but if that's how he felt fair enough, I guess I'm just very bad at sensing what other people need unless they explicitly tell me. anyways I messaged his gf and she responded something along the lines of, it's really sad it's come to this, don't take it personally I think he has a lot of shit he needs to sort out in his own life - if he could have just said that to me I would have had a lot more respect for it.

Anyways we still talked very occasionally, but she liked my social media posts quite frequently and I thought was all cool, only to find out yesterday she too has blocked me on like EVERYTHING, I should clarify she has a semi big following online around 15k, anyways we hardly spoke and I cannot for the absolute life of me think what might have provoked it other than feeling awkward about the bf situation I guess I don't know, I wish I had some clarity. I guess I'm sad because I NEVER had any Ill intent to the either of them and I feel as though I've been painted to be a villain.
