Major crisis!!

[BallisLife24]

So Saturday night I went to prom with my girlfriend and I was expecting it to be perfect. However things went bad quick. While waiting in line to enter I happened to catch a glimpse of her text messages to find that she had been having a most recent conversation with a guy named "Michael" with a heart next to his name. So I asked who he was and she kept replying with "hes a friend, don't worry about it" but how could I not worry? My name doesn't have a heart next to it anymore. So I asked again and she said "it's no one" and I wasn't convinced and was becoming angry so I asked "are you cheating on me?" And she said "no, I would never do that" and I truly know she wouldn't but my anger and jealousy was rising quick and I was just dying to know. Well when she kept refusing to give me more information I completely began to ignore her. I have her the silent treatment for about half an hour. Then something occurred to me...
I asked "isn't Miguel your ex boyfriend?" And I was almost positive that it was but she said "what? No, it's my friend from north" (another high school in the area) and I said "why does he have a heart next to his name and I don't?" And she said "I've had his contact name saved for a long time. So I asked "what were you guys talking about if I may ask?" And she said "he text me to tell me to have fun because he knew my prom was tonight" and I believed her.
She has never lied to me, she has never had a history of cheating, let alone a history of being in relationships. (I think I'm only her 2nd boyfriend) and she's been cheated on before and so have I and we agreed that it was the worst feeling in the world so I doubt she would do that especially since it's been done to her as well. And on top of that shouldn't her simply telling me she's not cheating and that he only text her to wish her a happy night? I mean he must know she was going with me right? I should believe her right? I'm not stupid and falling for a lie? If anyone deserves my trust it's my girlfriend whom I've been with for about half a year, right? HELP ME?!

I don't think you have anything to worry about. Sometimes its just best to let people have there secrets. For instance, you wouldn't want to have to have a long conversation about your friends with your parents, even though you love them, right?

As far as I can see you have no reason to worry. The fact she was cheated on makes me think she wouldn't do that to you since she knows how much it hurts.

Good luck :)

I think it's fine, but keep an eye on it. All that jealousy is normal between young couples, and in the right amount it's even healthy. Try not to be too intrusive, but don't let yourself get fooled. Just continue acting like nothing's wrong (and probably there's nothing wrong in fact) and see how the relationship evolves.

I don't think you're falling for a lie...you're somewhat right to say you are jealous- but in this case, I also think you're wrong. Observe her a little more while being inconspicuous and if she keeps flirting with other guys (while you're with her of course, acting as a "friend") then something will be up.

Don't be too concerned about it or if you are really worried about it use that to work on your relationship instead.
My last girlfriend had a good friend while she was dating me, I made the mistake of just becoming jealous about their relationship which just pushed them closer together as she didn't feel like she could talk to me anymore.
Make your relationship with your girlfriend as strong as it can be and you don't really have to worry about much else, focus on you two, don't worry about other people unless you really have to.

Agreed, you should keep your eyes peeled, but don't forget that people DO need some privacy, even from the closest person. And don't necessarily jump to conclusions; just because she texts another guy, it doesn't mean she's cheating on you or that she has any interest in him. Despite what is being said, teenage guys and girls can be friends, with no romantic implications or interests whatsoever.

Thank you all, that really helped to ease my mind and take away my jealousy
