I am the same way, but i always hear that keeping things bottled up inside is not a good thing. I think you should talk to this person about this a bit more. i can't really answer ur question i myself is only 14.

I don't know one teenager who likes their life. None of us did when we were that age. There are alot of changes at that time of life, hurts, frustrations, you name it. The best advice I can give you is to never let a man control you with manipulation, sex, or any other way. Your boyfriend telling you he will kill himself is his way of holding you. If you no longer have feelings for him, then you need to tell him. and move on. Tell him that you will not be made to feel guilty for his threats. If he persists, he needs to see someone, because he is mentally unstable. It's not your problem to be his everything. Give it to him gently, but straight, and MEAN IT. You can't keep giving mixed signals by coming and going. Make the decision and stick to it. If he bothers you for awhile, ignore him. This kind of relationship scares me for kids because there are alot of unstable ones out there, and can erupt in violence. So make the cut honey, try to be gentle but firm. Teen years are pretty easy to get through in one piece IF you make the right decisions. And you will be glad you did, because you don't stay a teenager for long, and once you are an adult, the sins of the past can come back and haunt you.
