I really don't know where to start with this, my head is seriously messed up.
There's this girl who I know briefly to say hi to and have a joke with who I hadn't seen in ages. At the weekend I started randomly thinking of her and I couldn't get her out of my head. Then today, out of the blue I saw her when I was walking home from school, we talked for a while and I got her number.
The problem is that I have a girlfriend who I really care for, she's great and I love being with her but I am becoming more and more obsessed with this other girl. I really don't want to break up with my girlfriend and I don't want to hurt her by cheating on her but if the opportunity arises I don't think I could turn this other girl down.
I just feel so bad about this. Why am I so obsessed with this other girl even though I am happy in my relationship?
