Hi Rafaelle,
Looking back, this also happened to me but slightly different as sexuality was also involved. Back in 2007 I was in a gay relationship with a man. I was still trying to be a man and overcompensating as we do (truck driving, metalworking, etc) but I felt really girly when I was with him. Anyway, after he dumped me I got into a relationship with a woman on the rebound and just wanted a 'normal' life. Put all that behind me. But this was not to be as 10 years later, the pressure finally got to me and I started having memory loss, pain in all my joints, fatigue and severe depression to the point of seriously contemplating suicide. This all cleared when I finally admitted to myself that I was trans and that I have no sexual interest in cis-women, only men (or some transwomen).
As soon as the 'love' haze cleared in my relationship with a woman, my true feelings surfaced many times stronger than before and I think this is a very common situation.
My wife won't accept me as a female and so there is no future for us and I cannot perform for her as a husband, which leads me on to the fact that she doesn't really love ME. She loves what I represent to her and that is a man who can make love to her which I truly am not and cannot. I have not deliberately deceived her as for years I genuinely did not know I was female inside and what that meant. I loved being girly but it was my 'dirty little secret'. I told her about my sexual past with men and that did not bother her.
What concerns me about your situation is that you may end up repressing your femininity successfully for a few years only to have it rear it's head up stronger years later when you are in a relationship with maybe kids, a mortgage and all the other complications. At that time it may be strong enough to literally take over like mine did. No matter what I did no suppress or ignore it, it physically took over my body and made me ill to the point it was affecting my work and therefore my ability to keep a roof over my head so it gets VERY serious.
Please take time and talk all this through with a gender therapist as this is SO important for the rest of your life. It's harsh to say, but partners can come and go but you have to deal with you for the rest of your life and you have to be happy and comfortable with yourself.
Take care,
