So my girlfriend and I have been together for about a year now. We both attend the same university and see each other every day. We are very open with each other and have talked several times about marriage sometime in the future. Things were going fantastic, until one day when her roommates (who are all guys and friends of mine) threw a party. She met these two French guys there, who for the last 2 weeks she has been flirting with continuously. I tried my best to ignore it, but coming off a long term relationship previously in which i was cheated on, I started to get paranoid. I started noticing small things that had happened just before the end of my last relationship. Things like not kissing me as much, getting annoyed by my affection, no longer wearing jewelry I got her, not wanting my arm around her at the movies (only when we go with the French guys), and lots of other little things like that. I started going crazy after a few days. My jealousy was making her feel claustrophobic in our relationship and made her feel like i didn't trust her. All of this made her act really weird for a few days. Just disconnected, quiet, all things that only scared me more. I got scared because of all the signs mentioned earlier and explained how i felt and why. It helped a little, and we both agreed that we still want to be together for a long time to come, but things were still weird between us. I started to think that maybe i was just being over sensitive to things because of my past experiences. I wondered if i was seeing things that weren't actually there because of my jealousy. We finally worked it out and talked about it for a long time. Things are now 99% back to the way they they were before and we are both happy. However, she did finally admit that she is attracted to one of the French guys, but would never act on it. She just really enjoys the attention. While i still feel bad that I made her feel so claustrophobic by being jealous, I cant help but feel that i had the right to be....since all of those little things i noticed turned out to mean exactly what i thought they meant. I'm not looking for "am i right or am i wrong" here...just some feedback on how to handle this sort of thing in the future and not let it happen again. For all i know it may be me who's tempted next time.
