I don’t know what to do😅

So this may be long but I really do need help so if you read until the end, I appreciate it sooo much! Anyways. My boyfriend and I started dating when we were 17, after about 8 months of being together I got pregnant and our lives completely changed. We were 18 and in college and living in his moms house together and I didn’t even have my own car yet so it was super super stressful on us. He was used to going out with his friends and having fun and not having any responsibilities and I know it’s harder for boys to mature so I’m trying to be understanding. Were both 19 now and our son is 2 months old. Last night he asked me if I though our relationship was good and I said no and he agreed. The truth is it’s not, I think he may be depressed. He never wants to pay attention to me, he’s always on his phone or playing Xbox. Basically anything to distract himself. He doesn’t even want to eat anymore. He has no interest in going out and doing anything, he just wants to sit at home. Like I said I know all of this has been super hard on him. I adapt to change really easily because I had a rough childhood but i understand not everyone can do that. I told him I thought he might be depressed and it was okay if he was, I suggested we take some time apart from each other and he go stay with his brother who lives in another state for a few days to clear his head and vent to his brother. He says he’s not a pansy so he won’t be doing that. Our relationship won’t last if it continues the way it is now. I try to be understanding but I’m the only one trying now. I don’t really know what to do. I love him and he’s my best friend but Idk if he doesn’t love me anymore or if he’s just depressed🤷🏼‍♀️

Edit: he watches his child 8 hours a day so I am able to work. He watches his child and he loves him. Thank you
