<human>: Can you condense the text into three sentences or less?

I am currently "male," however I do not wish to be.  Ever since I can remember I have felt like a girl, a tom boyish girl but a girl.  I believe my family will come to terms with it eventually, even my two brothers. The question I have is what should I do about my girlfriend? we have been dating for 2 years. During this time I have been trying to suppress my feelings, thinking that maybe they would go away but they have grown and I feel more now than ever that I should transition.  I have told her that I love her (and I do love her) and I told her that I want to marry her and have kids (this is the lie).  I thought that I could learn to want this.  I don't want to be like this, I feel like a freak at times, but I cannot help how I feel.  The main reason I'm asking reddit is because we are currently in college and I was wondering if I should wait until the end of the semester or until the end of our senior year? I don't want to hurt her I do love her, she is my best friend, I'm just not in love with her.  I don't want to cause her to become depressed and have troubles in school or flunk out, I do believe that is a possibility.  She is madly in love with me and I know when I come out it will break her heart, I don't want it to ruin her life if she drops out, but at the same time I don't want to wait as the longer it goes on the more it will hurt her when I tell her.  I also don't want to wait too long as I am 21 now and the longer I wait the harder it will be to transition successfully. So reddit, any advice would be greatly appreciated.
