Me and my boyfriend have been together for 2.5 years. He broke up with his ex about 3 years ago because they were long distance. He tells me they text every 5- 6 months as friends. He tells me there’s no feelings, they’re broken up for 3 years, he just wants to remain friends. She is aware that he is in a serious relationship and knows everything about me and always asks about me but still Every time he tells me they text, I get very upset and hurt. I dont want there to be any relationship even as friends with his ex but he doesn’t listen to me.
Couple days we were at lunch and he told me they were texting and that she was asking if me and him are engaged by now. I asked to see the texts and he said no, so I just took his phone and went in the women’s bathroom. I go through the texts and she was talking about their past relationship, how she wants to be more than friends with him, how its so hard for her because of her feelings. She sent him a good morning picture of herself, and his answer was “pretty girl 
)” .. then he sent her pics of himself too in his Air Force uniform. They were basically flirting all day.. Im just so hurt by all this, I trusted him when he said they were texting as friends and after stealing his phone I see it’s all a lie.. I see him flirting and sending pics to his ex from 3 years ago.. I dont know what to do, he says hes over the past and he wants to marry me but Im so afraid. I dont know what to believe if after 3 years theyre still talking about their past and they clearly flirted by sending pics
