U oh and you've having another baby with him? He sounds immature and has a lot of growing up to do....it's very sad that you're married to a guy like this and actually have two children with him - put the breaks immediately on to having any more children. Right now look after your children...
Jealousy can be cruel. Don't hang out with girls who are immature and have hangups. You really need to move on and find a group of girls that feel good about themselves and actually have fun - not by abusing others!
