HOW MUCH MORE CAN I TAKE?

Here i go again,stbx met our daughter today and me and my friend drove past him.He totally turned his back on me and wouldnt even look my way.Then when i caught up with my daughter she said hes apparently met up with someone on the internet and it looks like theres a new relationship for him again.She has 3 kids wich he will love lol.I was a bit upset to think he could move on again and im still not ready but the more i think about him the more i pity what a sad git he is and im actually embaressed for the children knowing that in 6 weeks hes had 3 serious relationships.In a way im glad as its proved to me hes not worth my tears anymore.
