Welcome back ladies and gentlemen of the internet. Relationships can take so many turns, ones you don't expect. You start dating someone, things are going smoothly, and then can just shock you in a moment with news you weren't ready for. People are surprising, and it's wise in relationships to weed out what's normal and what isn't.
Exes are also a topic of conversation. When dating someone new, there shouldn't really be a lot of contact with exes, I think we can all agree upon that. If there are, it definitely says something about their relationship. This brings us to the Reddit thread. This man has been seeing his girlfriend for not so long at all, and she has a kid with another man already. It's not a deal breaker for him, and as he's getting closer with her, she spurs on him that her ex (her child's father) needs a place to stay and will move in with her. Yeah, red flags galore. I'd break up with her too.
