Heartache again

The feeling of your heart breaking sucks, apparently the man I've been in a relationship with for almost 2 years was and is still talking to one of his exes behind my back. I thought he was different but I guess not, all guys are the same. Here I am yet again laying in bed crying and trying to figure out if I should tell him I know or wait and see how long it takes before he tells me, or if he even tells me. Until then the walls are going back up. I loved him so much but it's time to move on , I deserve better. Someone who will want to talk to me, who misses me as much as I miss them, who can't wait to see or talk to me every day. This really hurts, but I guess I'm used to it by now, and I'll get over it eventually.
