Idk how to feel....

My bf and I have been bumping heads a little lately. Nothing too bad but I can just tell we’re at a crossroads and we’re just off.

Well tonight I was telling him how I wanted to start eating better, especially after having baby I’m trying to get back in shape. I asked him how we planned to do groceries since he doesn’t eat as clean as i do. Well he found that to be a convenient time to say “well idk bc I’m probably going to be going back home.” And I was wondering why and he said his mom is having surgery. He never told me this prior. Even when he could have told me when he first got home today he never mentioned it. I get that and all but I feel like he has obligations here as well to help me raise our 4 month old son. He has a teenager sister that lives with his mom who I feel like can help with whatever his mom needs (since she’s not in school) but i feel like he’s just leaving us high and dry and trying to use this as a reason to get space and be away from me.

Now he’s having to go to the hospital with her and be in the nasty environment with corona and i have to worry about that now. I’m just feeling like I’m being put on the back burner. I know it’s his mom and he wants to be supportive and there for her as well but I feel like he’s not thinking about me or his son.

What would you do in this situation? I’m trying not to be a “bitch” or self centered but I just don’t think it’s fair for him to leave me like this.
