Jealousy, awkwardness issues.

For someone such as myself,I wouldn't leave the guy I'm in love with,especially if I know he loves me back, for some other guy who tells me that I'm the one.That would just be messing up a good thing,& I'm sure you're girlfriend probably feels that way.But,in my opinion, if you really wanna fix this, you should fight back.Not through physical violence, but through (excuse my cheesiness) wars of the heart. Your girlfriends heart, to be specific.Let her know that you will do what it takes to remain by her side, & you shouldn't do this just because of another guy trying to steal her away. Tell her or do 1 sweet thing every once in a while, but don't smother her, or she'll feel pressured, but do let her know you care.Just like you said, perseverance usually does come through in the end. You gotta work for it though man! : )

I'm going to do my best to answer these in the order you asked them,hope I help!
1.Girls, as we all know,get insecure, & tend to react to certain situations differently depending on the person. Your girlfriend(in my opinion) feels most comfortable when she's around you alone, because your her boyfriend & she loves you. But at the same time, when she's around others, her feelings are a bit conflicted. She loves you, but probably at the same time, she wants to fit in with her pplz, & uses you to do it. Also,did the fact that she may want your friends to like her ever occur to you?There's that fitting in thing again. Try talking to her about it, set some of those emotional boundaries. It might just work!
2.That just means you love her. Your never going to feel completely comfortable with her being around other guys, so your going to have to put a little more trust in her,& the relationship. It' s normal for anybody to get jealous when they love someone,but we learn to deal with it. Also, when you feel yourself starting to get jealous, remember that YOUR the one that's dating her, not those other guys.
3.No offense, but if you don't like the fact that she's being hit on & such, why don't you just stop beating around the bush & DEAL WITH IT. Just because other guys are trying things with her,it doesn't mean you should escape those worries in such a negative way. Do you even know if she's accepting those guys' offers?Again, this is where TRUST comes into effect. Besides,what's the point in giving up & avoiding the problem? Dude, this is a relationship. Both people have to put forth the effort to make it work,not just one. That applies to both of you. If you keep having troubles with this girl though, you should consider seeing other ppl.Like I said,consider before you act on one person's suggestion.If you really love her,keep working on the harder parts of the relationship, not just ignoring them.Best of luck!

I'd like to give you some ideas, but I don't know exactly what your asking. Your words don't make any sense here. add some updates so I can understand what your problem is and what your asking.

Well, I had the same problem in high school. There was a girl I would have 3 hour phone calls with, not a dull moment EVER, we would laugh, joke, and always have tons of stuff to talk about. However, behind my back, she talked crap, and even at school she was cold sometimes. Usually the answer is simple, like you said, peer pressure. She may have friends that don't approve of you, so when she isn't alone with you she changes how she acts because she's afraid of losing her friends. That was the case with me.

The end result will be she either dumps you and ignores you for good, or overcomes whatever embarrassment you cause her (sometimes the embarrassment can really be pain, pain that you're making her realize who she really is, and maybe she doesn't want to come to terms with it yet).

In my situation, my friend got rid of me. In the worst possible ways because part of her still wanted to remain friends, so it was like sawing off a leg with a rusted blade. It took months!

I hope this doesn't happen to you, just be careful not to upset her so she throws you out. Don't pressure her on how she is acting, she is likely very conflicted already. Give it time, it should work out in your favor.

Hope this helps, and remember, the reasons could be completely different than I have just listed. I'm just giving one side of the story. Good luck, and feel free to ask more questions.
