<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been going out with my girlfriend for about 2 years and I really like her/we get along great but she goes to a different sixth form college to me and lives about 25 minutes away so I only usually see her at weekends. This has been fine for the most part and we really enjoy meeting up and spending time together.

However, there is a girl at my college who I spend a lot of time with just me and her because we do the same subjects and we are really good friends. Recently, because: I spend more time with her than my girlfriend, we have similar interests and we get on so well, I have started getting feelings for her and it makes me feel really guilty. Also we both do acting/musical theatre and we both got the lead rolls and it meant we had to kiss a lot on stage which helped nothing. 

Also the added factor that very soon I will be going to a different Uni to my girlfriend which will move us further apart sort of adds a worrying end point to the relationship given the apparent difficulties of long distance (my brother had a similarly long relationship which faded out at uni). But also the girl who goes to my school will likely go her own way and it scares me that I may never get really close to her. Even though i really love my girlfriend, I have a feeling; be it desire or simply lust of wanting this girl and it scares me that in the future I might look back and wish I had at least tried with her. 

A few months ago this guilt got to be too much for me so I tried to explain to my girlfriend and it resulted in us taking a break/breaking up for a while but that felt soo bad and so I apologised and she took my back luckily. But now I'm scared because the same feelings seem to be returning. 

Im so confused with what I'm supposed to do/what is right?
<bot>: I don't see my girlfriend much and I keep getting feelings for a girl at my college I spend more time with.
