Is he lazy or depressed??? I don’t even know anymore

I’ve been in a rocky relationship for almost 4 years now. We have had fun and we have also had bad time in our relationship. It’s been all over the place. My boyfriend who I now have a baby with that happened while on birth control (I love my baby to death but I hate that procreation happened when I wasn’t or prepared for another child so don’t take this wrong I love my baby very much)…. Well anywho bf hasn’t been working and he’s had times like this throughout the years we have been together but right now it’s just been one thing after another. His truck messed up and there’s no work for him right now. He’s a subcontractor and does remodeling and currently things are backed up and work is just very slow apparently. Well now I’m scared we will get evicted. Can’t make ends meet. He makes not having a car an excuse to go get money. I just don’t see he wants to go make money. I’m getting ready to just walk out of this one because I seem to be holding on this entire relationship and I just don’t know how to help him anymore and I really can’t anymore it’s draining me… I try talking to him and he takes like an argument and just walks out on me… I have two kids to feed and put a roof above their head and I want to help him and I just don’t know how… 😔
