You can't. Unless the person is your own child, you cannot tell somebody who they can & cannot see. That's being petty & selfish. If you're trying to stop someone from seeing someone else because they're being harmed or you feel they're putting themselves into danger, you can contact authorities & tell them you suspect that the person needs help.
maybe he is the one that is seeing or sleeping with someone else. I think you should be asking him those same questions.
Yes.
he is probaly seeing someone else
No. A spouse or ex spouse cannot get an order to prevent you from seeing someone else. They could get a no contact order to keep you away from them but not someone else.
You don't go there.
Ask around. Someone knows.
Ask him, or follow him.
because he still misses you or he hasn't found anyone else or he has found someone else but this person could be somone that you know or very close with.
no it usually is because they are seeing someone else or their scared of change.
I guess I'd have to answer that question back with another question: Why would you want a man back after he has walked out on you and your children and is seeing someone else?
Only if he finds out.
you will know when he starts acting weird
