You’re alone in the sense that you’re dating a 30 year old man who lives in his moms house and has basically been grounded by his mom and isn’t allowed to have friends over

Is there a reason he’s ok with being treated like a child? It’s not a normal lifestyle to live. Why doesn’t he want independence?

It’s also kind of weird that you blame his mom for his brothers car being full of trash..plenty of people get takeout but they throw away the wrappers and containers

It kind of sounds like your boyfriend and his brother are immature and don’t value their independence. A normal adult in this situation would have just moved out a while ago or established boundaries
