This girl I'm seeing now seems to keep in touch with all of her ex's. One of them talked with her on the phone for about 3 hours, and asked her out the other day. I don't think he has another chance with her. I'm the jealous type but I do not want the girl to know that. I just got off the phone with her and she was hanging out with one of her ex's and a few other people. I don't think I can stop this but how do I start up a conversation about it without sounding jealous about it. I trust her, but just in case I got have a back-up girl. Please respond.
