Katie, I know your pain. I really do. I have been (and am still going through) the same thing.
First let me start off by saying two things:
1) Love hurts
2) Men can be blind and stupid
I know at first, when you see what he is doing now, it tears you up. It eats away at your soul. It makes you unable to think... only feel pain.
You have to understand something as well and try to believe it:
He is in as much pain as you are.
The 'flings' he is having with women .... they are only cheap fixes to soothe his pain of unloving you.
I made his same mistake once. I regret it till this day, but you must realize, I would not regret it now unless I had done it.
He is only human. You are only human. I am only human. We live and learn through our experiences. It makes me want to cry when I think off all the sins I have committed since my break-up. The only thing that makes me feel better is how much I have LEARNED from them. I was blind and foolish then. From this I have learned how much I truly have loved this girl and STILL do.
You CAN'T stop loving him. No matter what ANYONE says. The 'tips & tricks' only push the love down and down, and then you become COLD and BITTER. You become a monster. Eventually all that love that you kept pushing down and down comes right back UP. It explodes, and when it does, it is blinding, and you just cry, and cry, and cry. You weep, and then you begin to realize how important they were/are to you NO MATTER how much you try to FOOL yourself.
The pain is something you have to deal with. I don't know if times will ever heal it. Maybe you will always have a spot for them in your heart. Maybe the time will heal your pain..
Maybe down the road he may realize how important you are to him, and he will come begging back. Then will have to decide if you want him back...
Unfortunately I have to leave right now. I will hopefully finish this post when I come back from work.
Your brother,
