Ok there is another possibility which does equal being ghosted but doesn’t actually make him an arsehole for doing so.
If a poster on here (or a friend in RL) said that they were in a relationship with someone who:
Still lived with their ex therefore they couldn’t go round to the house ever or know where they lived
Couldn’t meet the kids
Could only get together once a week because of the above.
Most people would say that either: “he/she is married still and the ex isn’t as much of an ex as he/she says,” or that the situation is such a mess and so unresolved that getting into a relationship on any level is incredibly unwise considering. Given that he’s not been out with his friends before is it possible that they’ve heard about the relationship for the first time and have advised him to run, even to ghost you if they think that you’re still legitimately married and have not been truthful with him?
FWIW I’m not accusing you of lying, but your setup is incredibly condusive to people thinking that it’s not all it’s cracked up to be.
And in actual reality, this relationship doesn’t have any kind of future as it is. You’re still living with your ex (when will you be living separately? Do you have separate bedrooms?” He can’t come over to your house? Your kids are presumably unaware that you’ve split up and even if they are you cannot introduce them to him until you’ve been moved out for a considerable time so that’s not in the near future either....
As for the posters saying the OP should demand the ex come home to look after his kids so the OP can go out looking for a boyfriend she’s started seeing while she’s still living under the same roof as him, if my ex had done that I would have told him to do one.
Living under the same roof and having mostly separate lives is one thing, living under the same roof and rubbing the new relationships in the other one’s face is quite on another level and would be incredibly disrespectful, and no way should anyone have to accommodate that.
