OK so I'm 15 right yeah young I know but I've been going out with my girlfriend for a while and... I have so many things I don't tell her I talk to her friends about it and stuff they are also my friends too but when ever I tell them something they tell her and for reasons which I can't explain I just can't tell her anything and seriously every time she finds out from her friend she gets pissed at me and things in this relationship made me go suicidal I thought about breaking up with her... but I just love her so much... I don't want to lose her
And I have a feeling if I do break up with her I'm going to want her back. :(

So yeah.. im stuck... help me.
Please!!

Don't talk to friends she feels like you are going behind her back and then she has to constantly wonder if they aren't telling her really bad or really personal stuff too.
Also she must feel like you aren't taking your relationship serious enough if you can't communicate with HER. Going to friends might make her feel that you care more about the friends than you do about her.
You need to learn to talk to her. If you can't come right out and say something to her try and find a way to 'bring it up' and let her take the conversation from there. Like if you want to tell her you aren't happy with the way she does something start discussing what do you think the best way for couples to get along with each other is when they have a disagreement? Or for your problem talking to her ask her what kind of things she feels are important in a relationship. Just start talking about things and the more you communicate the more comfortable you will start to feel about telling her things you feel you have to go to your friends for.

Any female will feel bad if she has to hear things from her boyfriend through her friends. Stop talking to the friends, and work on building the lines of communications with her.
