I think you might want to combine two threads. I replied to your other one. You can’t make her go to therapy if she does not want to but you yourself would benefit from therapy.

She sounds like she is an addict. Staying up all night gaming and chatting with guys while having full time job and a teenager at home, even if she wasn’t married, sounds absolutely ridiculous.

As with any addict, is it alcohol or drugs or gaming or sex, healthy relationships are not possible.... unless they seek help. You can’t make them though

If it’s jointly owned house do NOT move out. No way. It would be different with rental. Also, do you feel unsafe? If you don’t feel unsafe, I’d refuse to be invisible in my own house. Is this 30 year old the same guy who is coming to visit her in person? I wonder if that’s why she wants you out of the house

14-year old shouldn’t live like this. I am sorry you are in this predicament. Unless she seeks help with her addictions, I am not sure what could be done
