He’s said all I do is complain..

My bf and I were separated for 8 years, we got pregnant very young. We reconnected and decided to move in together, the first 3 months were great. Now 7 months in the affection is hardly there and the sex, I brought this his attention. He said he’d work on it but nope, he’d rather go hang out with his friends and neglect our relationship. Today I had it, I’m always doing homework with my daughter, I pay for her activities, she has a project due this Tuesday. I told him we need to finish it, he gets home and I say okay after this show let’s help her, he then says “so and so wants me to go to the gym” and I lost it. I told him it’s always me doing everything with her, it’s overwhelming. He only does homework with her when I ask him too, he never offers to pay for her sports unless I ask him to help. When I said that he got defensive and said I complain about everything, I’m always mad and I always have something to complain about.

I complained about intimacy and affection because I was so afraid of us losing our spark. He said all I know how to do is complain and I started crying. I never wanted us to go left but I feel like we’re heading there.

Was I wrong for “complaining too much”?

Edit-

Should I leave for a couple of days?

I don’t see how this is going to work now that I won’t feel comfortable communicating with him.
