Nothing wrong with it at all, but still tell your man if u want.

There's nothing wrong with talking to an old friend, but you shouldn't keep it secret from your boyfriend. Also, if the old friend is starting to get interested and wants to move to be near you, you need to tell him you're just friends.

I come up against this a lot with my girlfriend. Even after a year of attention from me it is still hard for her when she hears me say the name of ANY woman. I have always had a lot of female friends, and I'm friends with most of my exes. I know that If I never mention them and go about my business then the inevitable ridiculous fight won't start. But that isn't my way. To me, a relationship isn't something that binds another person, stifles them, or constricts them in any real way. These ladies are my friends, regardless of whatever my history is with them. I trust my girlfriend because that is how I know to make a relationship work and she has earned that trust. She "knows" that she can trust me, but she has some fairly large insecurity issues from the numerous guys that cheated on her with their exes, or just cheated period. To her, the idea of being friends with an ex is as ludicris as wanting to see how much it hurts when you stick your hand in the fire. But she knows that I am trust worthy, that she gets the vast majority of my attention, and that she is who I want to be with...but I still need to be myself to be happy. She understands that and is working through her insecurities.

For you, why do you really feel like your man will have a problem with this? If it really is just a really old friend that nothing happened with and that nothing will continue to happen with then this isn't the type of thing to keep hidden. My biggest concern would be why your man may not be trusting of you, unless he just wants all of your attention, in which case he needs to grow up. Does he have some reason to not trust you, or is it just out of insecurities like my girlfriend? Just as important, do you want to be with someone that will stifle who you are? Friendships are important to all of us, and should never be given up for anyone. Give up a friendship if its abusive (although that really isn't much of a friendship) or toxic, but not because your SO is insecure.

For your old friend moving into your city, was this just happenstance? Initially it all sounds on the level and innocent, including his giving you his number. Its great to re-connect with old friends, and if that is all that this will be, then just enjoy seeing your old friend again. Purposefully hiding that you are chatting with this friend again is wrong. It creates problems. If there isn't trust in the relationship then there isn't really a foundation there to grow on.
