Realizing I'm a married yet single mom.

It took reading a blog explaining this to make me realize that even though I'm married I'm a single mom. I feel more like room mates. There is no date nights because he'd rather hang with the guys or his brothers. When I brought up me needing help and time to myself he said I signed up to be a mother and that means no time for myself. Makes me think he doesn't want to be a dad if basically saying kids are only my responsibility to take care of. I never ask him to do something because I'm used to being let down. He constantly complains our toddler not used to him but its his own fault but if I say anything he starts basically manipulating me to say he's a great dad because he starts getting sad and saying he's a awful father and I get annoyed so I say what he wants. If by end of 2021 nothing gets better I'm going to ask for a separation so we can take a break before fully considering divorce if separation doesn't help.
