I’ve been reading why does he do that? by Lundy Bancroft and it’s a really good read. It’s making me think of the behaviours which should have been red flags to me when I first met him.
I didn't have that book back when I needed it, but a similar experience to you, I hit a lurching realisation that I was somehow the common denominator in all my relationship woes - luckily most of my ex's were just common-garden-variety selfish arseholes but a couple of them were also very controlling and the last one, violent.
I signed up for counselling and luckily my counsellor was very tuned in to the root of why I gravitated towards those men. Just as I gravitated towards selfish men of all flavours, they in turn gravitated to people pleasers like me. Not unlike my parents. I realised that much of our relationship teaching are learned at the knee.
Towards the end of my counselling, I was set up on a date with a colleague's flatmate and almost immediately I saw red flags and subtle tells that I would have previously ignored or brushed off. The old me would probably have drifted into a relationship with him but the new me didn't get past the first drink...and I didn't even make up a fake excuse to leave, I was assertive, and firm, telling him that I didn't see us going anywhere, and best cut our losses now. Man he was really pissed off, which only reinforced my red-flag bingo full house really! After that, I knew I'd be ok and I was right - and so will you.
