I just ended my 5 year relationship w/a guy that has always cheated on me

He tried to get with my friend and I believe that was a sign from god because she turned out to be fake and actually fell for him as well.

He has cheated and has slept with a girl I went to school with.

He continues to lie and I continue to let him lie to me.

He went on a date TWICE with his ex while I was working

I broke things off with him and he’s acting like he doesn’t care which KILLS ME INSIDE someone please tell me everything will be okay 😪😪😪
