my ex and his new gf

Maria
So my husband and I have been together for 2 years and almost been married for a year. Before we got together I was with his best friend and it's a complicated story. But anyway when matt ( my husband) and I got together his friend (my ex)  found out he call him and told him it was ether him or me. Ovoisly he choose me. For 3 weeks my ex wouldn't talk to ether of us and then out of the blue he ask if we want to hang out. Well now everything we hang out his new gf alway has to bring up the past and how much she wanted to fight me but plays it like where the best of friends. It's really annoying and I hate that when they come over it's always the same thing they all hang out like nothing happend and it agervates me that my husband is just going along with an I wrong for being upset about this.
