I'm starting to doubt myself in Whatever

I saw my therapist today and we discussed my current romantic relationship like we do almost every session. See im dating someone who we believe have borderline personality traits and it’s taking a huge toll on me. We have been together a total of 3 years but broke up for 6months in the middle of it… basically for the same shit that’s happening in iur relationship currently. I’m trying to hold on to the pieces of myself that are still apparent and working on the parts I’ve lost sight of. My issue, whatever I do is criticised to some degree. Everything is always my fault and he is never to blame. His whole life “sucks” and he “can never catch a break”, which is far from the truth. I only work about 20hrs a week so I’m supposed to cook, clean, take care of the animals, do laundry, etc… like a housewife. I would normally have no problem with this, but since my partner is almost never happy its very difficult to please him. I could have the house spotless and its not good enough. If i dont have an idea for dinner he won’t give me a hint of what to make (he’s a picky eater so meals are quite boring in my eyes). Every little thing he does is starting to annoy me. I havent had sex in AT LEAST a month (and im sure im being stinje on that number) but he blames that on me completely. Im told more than id like to hear that I dont appreciate him or respect him, when thats most likely true on his behalf.
Instead of continuing to blab about things he does and doesnt do I’ll say this… I’m starting to take what I said to him when we got back together more seriously.
1. Spend more time with my family
2. Continue therapy (he needs it, and agrees but is now full of excuses)
3. Communicate more clearly
Those are the important ones.
He only comes to larger family gatherings, which make him feel uncomfortable, and ignores smaller family gatherings where he’d be able to get to know my family members better. My immediate family sees how much I’ve changed and don’t like it. I’ve lost weight (im now 98lbs at 5‘2.. or at least thats what the scale said the last time I checked), I cry daily, I’ve lost my motovation for exercise, and have gained even more self esteem issues which is very frustrating. I’m reminded how thin I am, which I hate. My boyfriend has told me I won’t gain the weight back, which is very discouraging. I’m always tired, ALWAYS! I can’t feel a certain way (anger, frustration, etc) if he’s feeling the same way. His feelings trump mine everytime. I’m about over this constant mind game.
