My ex was controlling from neediness and clingyness.
I couldn't read a book without him asking what it was about and being jealous of it being more interesting. I stopped reading, it was easier.
I love painting, same issue. Critique my work, make suggestions. I just wanted some me time. I stopped all of my crafts. It was easier.
I couldn't go out without coming home to a guilt trip or catastrophe. A guilt trip because he had been alone, had done x, y, z. I stopped going out in the end. It wasn't worth it.
Mt friends didn't want to come around because he was always present, listening, in a sickly, overly helpful way. Intrusive on privacy, but oh what a nice man eh? They stopped coming.
We argued about once every 3 months, always the same things, he would always promise he would change if I gave him the chance. He would be much better for a month or so, then get snippy, then once challenged, get ill/dependant.
He would do anything for me, like get water as you say, because all of these little favours add up to a debt of guilt. You feel like the unreasonable one. If I did the washing up, he would re do it properly. It undermined my knowledge that I could actually do all of these things for myself. It made me feel like I needed him. I gave up trying to do anything for myself or escape.
When I tried to leave, he threatened suicide. He begged, he needed me, he would do anything blah blah blah.
I left. He raped me. I got pregnant despite the MAP. He found out by going through my bin bags. Normal eh?
Sometimes control looks different to what people expect. It can be someone who you believe needs you to survive. Without you they would have nowhere to live. They have no family/friends. They depend on you and you owe them. Over time it wears you down and you stay because of guilt, not happiness or love. This is codependancy. It is unhealthy.
If any of this rings bells with you, please escape. You don't owe him anything or need to feel guilty, he chooses to do those things, he isn't your child. You aren't his mummy, responsible for him for life. You can do everything that you need to do to survive on your own.
If it doesn't ring true, maybe you just need to talk it through and mean it.
