There is this guy who I have strong feelings for. He has been dating a woman on and off for years. I know she does not love him. She just uses him . Long story how I know this.anyway his family hates her also. He is so mad at me right because he thinks I did something to him. How can I get him to forgive me. Also I know if he forgives me it will be up to him.. also about this woman. It is up to him when he realizes all about her. She has said things to him about me that are not true.. HOw can I realize things happen for reason.In the end will work out... how do I let this go..

T-I-M-E.

Not easy. Sorry.

But the fastest way is: You must run "clean" for at least 90 days to get clear head.

"Clean" is no texts, calls, emails, photos, or talk of him.

The brain will do a lot of work but you must log the days.
My breakup guide (below) has some useful thoughts in it too.

Hang in there!

Stop all contact with him, and do things that make you happy without his presence in your life at all!

I'm confused by your statement. It sounds like you want to be with him yet you want to get over him. You got to pick one.
