What more can I do? 26f 28m

I 26f have been living with my 27m ex for a bit. We’ve been making it work as friends/roommates for a while now. We’ve gone through a lot and have had a million talks about what worked/didnt work, what needs to change, and what happened. I’m not the best with picking up after myself (clothes, mail, my daughter’s toys etc) and keeping up with things I say I want to do like go to the gym and what not. He’s been getting annoyed with that and brings up how it was also a problem in our relationship. I have really bad ADHD (unmediated, in the works) and I’m bipolar (medicated). I do my best to remember the things I say I’ll keep up with. Having a four year old and two jobs and a million other things to deal with pushes back picking things up around the house to the back of my mind. I cook and bake all the time, I clean the dishes, take out the trash, pack his lunches sometimes, buy things/food I know he likes as some type of thanks, and try my best to stay tidy. I just ask him for MULTIPLE verbal reminders so I can stay on top of things.

He has set some boundaries like us not having sex for alllst two years but recently started initiating and we have done it multiple times over the course of a month. He talks to a lot of women and I’m sure he can do that with them as well have an issue with that before. He comes in sits in my room or stands in my doorway to talk or even asks if I can cook something specific. He goes back and forth on what kind of attention he gives me and how he treats me. It’s never anything negative but just seems uninterested in me in general sometimes. When I pull back or go out more often he seems to be more “clingy” or wants to do things like go to the store together or watch a movie.

We were texting and he made a comment saying that things work have to change if we were to date again. When venting to my friends, therapist, and one of the counselors at my job, they all say that one, I should stop and two how they are confused as to how I’m still not enough. They mention my personality and how anyone would be more than lucky to have me and how he will realize what he’s lost once we are officially separated once our lease ends this summer. We had a talk and I can’t see how those things make me so undatable. I have a young daughter who has been around him since she was a baby. He made a comment about how their bond has to break to which I reminded him that it’s his decision that is leading to us not reconciling and that’s what prompted him to talk about things needing to change (which before he says that he’s completely done. He flip flops with that too) I do all I can to be a good roommate/friend, mother, and person all around. We have a lot of the same interests and can hold conversations for hours or just be in each other’s vicinity. I don’t know what I’m doing that’s so wrong in his eyes.

What more can I do to fix this?
