<human>: Now I know at this age hormones are very much still a swaying factor but I want the same advice you would give to someone older than me in the same situation.

For the past almost year my girlfriend and I have been dating it has been nice. We do couple-y things and all the like. Not once have I really looked at another girl and had any feelings for her past the very skin deep things you feel for other people.

At least I hadn't until recently, our one year anniversary is coming up in December and I feel she's more into our relationship than I am. Not to say I'm done with the relationship or her but my feelings have sorta flat-lined where as hers haven't. Also recently I've been talking more and more with one of my few close lady friends and have begun to feel slightly attracted to her.

We have a class in common and most of the time when we aren't working in said class we're talking about just whatever. We share quite a few common interests (that I don't share with my current SO but that she accepts are part of me) and joke around about similar things. I haven't been seeing myself and my current SO staying together for too much longer after our one year (for a few various and complicated reasons) and want to know what I should do. 

Should I cut it off early and let my feelings settle before going ahead or let my current relationship slowly die and then figure out what to do.

I know I already posted this but  I wanted to post it again a little earlier in the day to get some more feedback (not invalidating the chaps or ladies that gave me input the first time 'round but there's strength in knowledge)

Give me the gist of the text in a nutshell
<bot>: Should I cut off my current relationship to let my feelings settle and then (maybe) go after my friend that I'm feeling this for or go back to my SO (after thinking things over)?
