not watching son

So yesterday my husband told me he is not going to suffer this weekend because I wanted him to watch our son. This dude don't ever like to watch our son. He thinks it's a chore. I do everything get him ready for daycare, get all his stuff ready, plays with him, put him to sleep every night, I DO EVERYTHING! I have to somewhat beg him to watch him to get a lil homework done & when I do that he asks how long I'm going to be. Basically I have two weeks off of work & he does too. This week is my finals & my son only went to daycare twice this week. This morning he told me he is not going to watch our son at all this week so I can get my finals done. Like wtf.... why? I'm pretty much done with this marriage. I'm only still here because I don't even know why. He doesn't even sleep in the same bed as me & hasn't since my son was born.. & he is 6.5 months old! Smh 🖕🏾🖕🏾🖕🏾🖕🏾 FYI. We both work full time, we are in the military & we work the same hours!
