I feel you man.
I mean, I have a girlfriend now, been dating for a few months, talked about marrying, kids, etc. Everything is pretty dead loving set for us. We're both sarcastic starfishs so we get along perfectly. And the love is great.
But yeah, I feel you. Back in my freshman year I had a girl like you, she was okay for a few months, had love a few times. She was a year younger than me, me 15 and her 14. However, close to the end of the year (I think like a few weeks away) I found out she went to one of my friends house one wensday night while I was at home helping my mother make dinner and had love with 3 different guys. Once I found out, she stopped talking to me so I just came up to her one day at school and said it was over.
I then asked for a reason, promising I would leave her alone if she told me.
"I liked the love."
Weeee fml.
But now, everything's all good. New girl, I loving love her. I actually plan on marrying her soon.
Slight problem, we fear she might be pregnant. I mean, we've always talked about kids, so we don't regret it, of course not.
Anyway enough about me. Khorde. I would say you just have to do what you think is right to stay afloat in the sea of despair. Do anything that keeps your mind off the stress and keeps you busy. Staying busy relieves stress. As for finding a gal, you'll get there. Just as I did, you'll find another girl. Good luck, bro.
