My husband called his ex while we were seperated does it matter?

My husband has always talked about his ex girlfriend since I met him usually when he is mad or drinking One time drinking he told me I had a queen once your not a queen. Other times he'll say he doesnt care about her because she cheated Long story short he came to this country in 2000 from colombia the plan was to get a good job so he could bring money bk for them to live on They were suppose to get married after a few mos here the calls stopped and she confessed she found someone els. 2004 we get together he made a phone call to her early in our relationship I was pissed Anyway last nite he confessed in an argument when we were split in 2008 he called her He was visiting his mom in colombia who was sick I had his daughter here and he wouldnt give me his parents #. In my mind that was so if they dated down there no odd phone calls would come from me.Anyways for two yrs he lied about even contacting her Turns out she was married and had a daughter To me if she hadnt been married he might have never come bk home to me I feel like the last two yrs has been a lie like Im second choice. I mean why was he trying to contact her in the first place??? Then when he came backfrom colombia he wanted to movebk in he bought me perfume clothes ect because he walked on me a yr before he want down there. Also i have a facebk and he erased the family pics of us i put on their. He says he doesnt want his face online because he's in military but so is his bro and cousin and they got pics on their site with their wives and kids Im wonderin if this has something to do with her I cant come up with another reason. what do u think of this whole thing?
