This is a timely thread. I have spent today feeling ridiculously angry- OK, partly because I'm tired because DS2 had a bad night last night, partly because I'm fasting (5:2), but mostly because my EA ex is seeing someone new.
Thing is, it's been almost 2 years since I ended it (when I was pg with DC2), but during that time he has spent a lot of time with us- yes, it's been helpful with a small baby, but it also means I've had to be his verbal punchbag whenever he had an outburst.
Over the course of a year I've managed to claw my space back, but it's meant a nasty argument when I told him he had to stop sleeping over at mine, a nasty argument when I told him he had to have the kids at his rather than playing half heartedly with them in my living room while I ran around doing all the housework and cooking all the meals, etc.etc.....
And now, he can just move on scot free and be having lovely new relationship fun, even though he's the abuser, and the one that caused the end of our relationship! While I currently feel worn out, unattractive, and overweight- from having his baby. And also having little hope of meeting someone decent- it just seems to me that all men have their nasty side, especially the ones that happen to be single in their forties 
It's not fair, is it?
