BabyMommas vs Gf's

Ladies let us help each other out. I'm a babymother and I see way too many posts about men being inappropiate with their babymother and using the children as an excuse. Please share some redflags so these girlfriends/wives can open their eyes and look for signs he is still entangled with his BM. I'll go first....

1. No he doesn't need to SLEEP at his ex. house for the kids.

2. No he doesn't need to be paying ALL her bills

3. No he doesn't need to EXCLUDE you from family events (unless y'all aint serious)
