Ok, I very briefly dated a guy when I was 14 and he was 18, our families pushed us together. We found out pretty quick it wasn't working out, I thought he was a little creepy, and he wasn't interested in someone who wasn't interested in the birds and the bees.
So we've seen each other a couple times at church since, he apologized once for being an a-hole, in his words. So a couple weeks ago we started talking online--you know, how have you been, what have you been up to, etc. I told him about Jeff and us planning to get married after awhile, he told me about his girlfriend that he wants to marry. We were having these nice, intellectual conversations--he wants to move to Japan and cure cancer, and so for awhile it was nice to have those conversations with him. Jeff knew that I was talking to him and didn't have a problem with it.
So for the last couple days, this guy has been calling me every day and emailing 2-3 times a day. Then today he texted me and said he wanted to call me later after his girlfriend was asleep. That reeked of creepiness to me and now I'm really confused. I thought we could just chat online and be friendly, but apparently now he wants to chat online and hang out occasionally. And I'm getting creepy vibes from him. I really can't explain it and I don't know what's going on. Can someone please tell me if I'm overreacting and/or what I should do about him? (Jeff offered to move back here and be my bodyguard, but I don't think that that's the best solution right now.
