You seem so depressed, you need to cheer up, nobody is worth that much sadness and low self-esteem. Just don't go that way, everybody here on QL loves you.

I'll tell you some of the things you have surely thought about:

He is not a MAN. Just forget about him, you need to leave him, his presence close to you is toxic. Forget about what your friends and family says, if the blame you, then they're not true friends.

YOU are in control of your life, and you can do whatever you want.

I wouldn't stay with a cheater, no matter how much I loved her, I would just burn my heart and leave.
