Divorce... Kinda long, please read...

Okay so, me and my stbxh were married for alittle over 5 years... We have two little girls together ( 1 & 3 ) We were living with his mom when he decided to kick me and both of OUR kids out a month ago today for absolutley no reason at all... I've been a SAHM for 3 years so me and my kids got left with no car, money, job etc .... And he could care less... Well let's just say not even a week after we left he already had a girlfriend that he met on " Tik Tok " .... He's head over hills " in love " with her and that's his " everything " .. He's only met her twice and has already met her two kids as well .... He work's out of town alot for work so on the weekends when he's off his girlfriend drives 2 hours to spend the day with him and he spends all day with her and her two kids on the weekends instead of getting his kids.... He gets an attitude and calls me crazy and everything else because I won't let him have the kids when he's around her... He doesn't really know her and I don't know her at all... I'm tired of him being an a$$hole to me just because he's found someone new and doesn't get his way... Im by no means over him and still hurt by how he's done me and my kids... I don't understand how anyone can throw away 5yrs of marriage and their family over a new chick he doesn't even know....
