From the beginning, my boyfriend and I have been very open and honest with one other about our past relationships. He knows about many of the issues that led to the breakups with my biggest exes, and I know his perspective on what some of the biggest factors were that ended his last four-year relationship. He knew that I casually kept in touch with a couple of my exes, considering a couple actual friends, and I found out that occasionally he and his ex had text exchanges. It became apparent that she hadn’t moved on from him, though it’s now been almost two years since they officially broke up. Yet it never really concerned me because she’s never made a presence in my actual life…but that’s about to change. So now I’m left wondering how to deal with your partner’s ex who is still hanging on.
