Here’s the thing. You’re looking for an insurance policy. 😕 Relationships don’t come with them. 😉 Your boyfriend cheated on you a year ago with his ex, and this app you have on his phone makes you feel better about that infidelity and his promise not to cheat. Now, he wants you to get rid of it, and this is making you think he’s behaving like someone who wants to cheat again. Since you’re in your early 20s, it’s a pretty good bet he’s not interested in settling down. It would certainly seem that if he really wanted to make you feel secure, he wouldn’t care about the app, but whether he’s cheated, wants to cheat or will cheat, his interest in getting rid of your “security blanket” is a sign that the relationship is changing. You’re wise to consider this change in behavior as a flashing yellow light and you have to really decide if this is a deal breaker, or if you’re willing to continue dating him, given your history and this new act. If you do, then you’re going to have to figure out how to date someone who’s cheated on you in the past. This is a tough one, but people do it with time, patience and mutual commitment. If you don’t, then you have to be okay with the reason for leaving. The bottom line isn’t this app, though. It’s really about whether or not his interest in you has waned and he’s looking for an exit door.
