ExP and I split up for good 3 weeks ago and haven't seen each other since. He's moved 30 miles away and the relationship is definitely over this time. We were together for six years and engaged when the problems became too much and although I'm getting on with it I'm still hurting.
I found out he slept with someone on Friday. I was on a mutual friends Facebook profile and there was an open discussion on there hinting to what happened. I haven't moved on at all and it really hurt that all of our life spent raising our two DD's together meant so little. He hasn't seen our DD's in those 3 weeks either 
How do I not feel so hurt? When will this stop? I feel pretty desperate and there's nobody I can talk to who doesn't say that I'm better off without him. I know I am but the pain is still there.
