2 years relationship, but suddenly fell in love for another
I'm in a relationship with my girlfriend (I'm a 19 years old boy) for 2 years and 2 months now. A lot of things happend, to make me feel that I'm gay or bissexual, because I do like to "play" with my girlfriend (we did it when completed 2 years, it was our first time). My confusion started when we were close to complete a 2 years relationship. I was having the impression that I find out boys more beauty then women. Now, I had a dream with an old friend of mine (a guy) the day before yestarday.
I tried to masturbate (and I imagined him) and I simply could not get him out of my head. And, with no apparent reason, I'm finding my girlfriend "strange." This is the worst of all, because, I have nothing to complain about her, and still, I feel that at the same time I feel attracted to this old friend of mine I know since 2013.
I dont know if this is temporary or why I'm finding her strange, and I don't know if I should break up or not.

Hey there. 
Seems like it has made you really confused. Sometimes, figuring out sexuality can be long and confusing process. What do you think you want to do, keeping aside every other factors? And how sure arre you of it?

I gave up of breaking up because I noticed that I wasn't being myself. I love my girlfriend and have pleasure with her, and I should not consider anything like that because of a dream. Every "wet" dream I had before were with girls and the very first time I looked into someone with sexual intentions was a girl.
I did'nt recieved that dream because of two reasons: I'm fighting hypochondria, so I was kinda using this friend of mine as a "cure" and victimizing myself thinking that my acute kindney injury (that my doctor told me the year before that was caused by a virus) was caused by a psychosomatic problem and I'm also trying to control my libido and pornography (And no, I don't like gay porn.)
