So my gf of ~6 months broke up with me on Saturday.

We fucked for the first time ever (but we've done oral, manual, etc before).

I just turned 16, she is 15.

She said that she is under a lot of stress (2 jobs, bitchy mom, stupid friends, etc) and she said that she can't handle a serious relationship right now, and that it isn't fair to me if she can't focus on me.

She said that once she sorts out all of the bad shit going on in her life (whenever that is) that we can get back together, and that we will be best friends still.

Here are my questions:

1) Is her reason a valid reason to break up? Some of my friends tell me that that's no good reason, and that if anything that should make her need a boyfriend even more, to help cope with stress.

2) Do you think that if we stay close friends, that we still do have a chance?

Note: This isn't a "let's be friends mmk bai cyah l8r" and never talk to each other again type thing. She was the one who was wanting me to promise her that I would still be her friend.
