"Mine wasn't accusing me of cheating. With him, it was all 'perceived slights'. If he felt criticised in some way, disagreed with, or that I was being in any way distant, it would be all out war against me."
Oh my goodness, mine was exactly the same!! So many perceived slights that I tied myself in knots over, then slowly realised were completely bonkers and his reaction was totally out of proportion, have me flailing around trying to placate him through the silent treatment and sulking and huffiness and outrage at 'how disrespectful' I had been. Such behaviour is deeply shit and manipulative.
I've found the two books: Adult Children of Emotionally Immature Parents: How to Heal from Distant, Rejecting, or Self-Involved Parents by Lindsay C Gibson (https://www.amazon.co.uk/Adult-Children-Emotionally-Immature-Parents/dp/1626251703/) and also her follow up: Disentangling from Emotionally Immature People, to be incredibly helpful in seeing through this sort of stuff. It was a lightbulb moment for me. I don't know about anyone else on this thread, but I was raised by someone who was also very emotionally immature, so it makes sense I'd go for partners who were the same in adulthood. But the books were such an eye-opener.
The reason I kept going back again and again was because I hoped he would change and I didn't want to give up on him, for all my effort (and suffering) to be wasted if change was just round the corner. After reading (well, listening) to those two books, I came to regretfully understand that change wasn't really possible for my ex, and started to know that the only course of action left to me was to step away. That it wasn't going to be okay. The grief of this realisation was just horrendous, and I'm still in it now. There's still a small part of me that has a tiny flickering hope, which I'm just allowing to exist while not allowing to call the shots. I suspect a part of me will always love him, despite how badly he's behaved.
Ultimately, I really want to get married one day, and I got to the point with my ex where I realised I wouldn't have anyone on my side to invite, because they were all so unimpressed with him literally no-one would be happy for me if I announced I was marrying him. They'd all be cringing inside and have their heads in their hands. Then I thought, nah, come on - this is insane. You should marry someone one day you are PROUD to marry, someone that your friends love because they know you are happy and that person treats you well! For god’s sake. It's that gradual waking up to the fact it won't work out. It's such a painful process, especially when you have invested everything into the relationship, including your dignity and your friendships, you have lost friends because of it, you have lost the respect of others, your own self-respect. It's so hard to think, crap, I was wrong. After all that. And walk away. Anyone currently on this journey has my utmost respect and compassion. It will get better, and brighter days are coming.
