<human>: So some information, 
I have been dating my girlfriend for about couple years, and it has been enjoyable, although sometimes I'm skeptical. I'm no sure if 'skeptical' is the word, but I'll continue. I really think the relationship is more towards her benefit and happiness, but that's the way I make it. I suppose I don't mind that I don't get too much in return. It's not like she treats me like crap or anything, I just focus more on her than she does on me, so she can't be blamed for that per se. 
The other girl graduated last year, but she goes to college in the state, so we keep in contact. I let it slip out that I like her, and she let me know that she likes me as well. By our sources of communication it was difficult to tell how much she liked me. We talked about it a little and decided we didn't want to ruin our friendship with this whole ordeal because I'm dating someone. I can make conversation much more freely with the second girl, I think, she's nice, pretty, smart. Not that my current girlfriend isn't, it's just that I am unsure about the strength of our connection. The "other" girl is someone I'd like to date, if I had to, I'd even put forth the effort for a long distance relationship if it came to that. I just don't know what to do. I don't want to ruin my relationship or my friendships, but I keep thinking about the "other" girl and what it might be like to date her. What should I do? How can I get over the "other" girl?

Can you give me the gist of the text in a nutshell?
<bot>: I'm in a relationship and I like another girl. I don't want to ruin my relationships with anyone, but I can't stop thinking about her. How can I get over her?
