My boyfriend and I have been together for almost a year and a half now. We did have a month breakup about seven months ago where he ended up getting back together with his ex, who left him prior to us meeting. (They were only together three months before we met.) They were only back together for a couple of weeks and he realized he wasn’t happy with her and abruptly left her. He ended up reaching back out to me because he missed me and realized he had messed up. (I had left him.)

Long story short, we ended up back together. Fast forward to where we are today, and our relationship has been amazing. We are both so happy and are talking about the future – kids and marriage. I had no doubt in my mind about him up until about a week ago. He got asked to be the best man in his best friend’s wedding, and the bride’s sister is his ex and will be the maid of honor. I will be a bridesmaid.

He saw her for the first time in seven months and has feelings for her. He’s very honest about his feelings, which is why I have always trusted him. After seeing her, he told me he didn’t know what he wanted or what he was feeling, and that he couldn’t give me all of himself. (This broke my heart because I love him and told him that if he couldn’t give me 100 percent, I couldn’t stay with him.) He ended up spending the next day by himself; he wanted some space and time to himself to get his head together.

That night he was a changed person and he said he didn’t want anything else. It made sense – we all experience emotions after seeing an ex for the first time in a while. The next day he told me she had reached out to him and that they had talked, and that it made him realize that he didn’t want anything to do with her and that he loved me and couldn’t lose me again. When I asked to see the texts and phone log, he said he panicked and deleted it. I told him I didn’t want him talking to her and that if she reaches out to him again, I want to see the texts. He agreed. He said it was an emotional conversation and that it was closure for him. But what happens when we have to see her again? He doesn’t really know the answer to this either. Should I let it go and be OK with it? I don’t know what to do. I feel hurt that he talked to her on the phone.
