Getting over the hurt and pain of my boyfriend's infidelity?

You honestly will start to feel better in that dear old word "time". As it isn't the foremost thing in your mind as it now is, it WILL get further & further into the back of your mind, I KNOW I also went thru it, In the beginning it's about all you can think of now at the moment. No, you honestly will never forget it, but as time goes by, things go well between the two of you, it will start to slowly not be in the front of your mind. One thing, don't "beat him up" over it. Try your best to let it go. Lots of times relationships actually get better after something such as this happens, You're trying harder to make things rite between you which actually bring you together even closer. I realize this may sound dumb, but try your best not to think about it as much as you can. You WILL overcome it in time as it becomes part of your past. Try not to let your mind "paint pictures" & love him for he person he is today. The past is forever gone, the future is still our own...the best to you...:)
