I would.
leave her. plain and simple.
When he/she cheats. When he/she doesn't want to work. When you feel like you have to babysit him/her.
I suppose. Absolutely
If a friend were in your situation, what would you advise?
no. he's a jerk, and you should leave him
YES. IMMEDIATELY. IT WILL ONLY GET WORSE.
You are better off without them
Honestly... If this person won't leave their partner, then that means that they are happy. You can't force someone to leave their partner because YOU love them. Either hope and pray that eventually they do leave their partner, or try and find someone new.
You should be able to trust your partner. There is no physical way to tell. You need to work on your relationship. Consider counseling.
A person who cheats may project their guilt onto their partner by accusing them of cheating as a way to deflect attention from their own actions and justify their behavior. This behavior can also be a sign of manipulation and a way to control the narrative of the relationship. Communication and addressing underlying issues are important in resolving these accusations.
Because the one who's cheating doesn't recognize that what they're doing is wrong and then gets mad at their partner. It's called being a hypocrite.
when you feel like your partner doesn't love you anymore and you feel like leaving him, you should confront him first or else, when you leave him and the truth was he loved you then that sucks before deciding,,, think first, do you think you're being a little bit insecure?
