I don't know, on the one hand LW seems pretty self-centered here - but on the other hand, someone whose reaction to exhaustion and stress is to shut himself in a room and play video games and refuse to address relationship conflict or do any kind of planning is also not someone I'd be excited about co-parenting with. (This is not an insult to LW's bf, it's what I do and I am not excited about coparenting with myself either.)
