His feelings change from day to day. How can I deal with him

His feelings change from day to day.
How can I deal with him being this what?
No matter how meny times I say it...
I will never acually be over him.
I guess in the end only one can ever win.
The way he makes me feel can never be matched.
He broke my heart and it can never be patched.
I constintly conpair other guys to him.
Why is it so hard to forget about him?
We used to get along so well.
Now she's with him and it all went to HELL!
How can I ever forget about what he has done to me?
He is my frist LOVE and I guess thats just how it has to be!
