I get really angry when I think about dating?

I get irate when I think of a lifetime of being with some guy I have to pretend to like, fake my attraction for and make feel like a king. I know most people need to fake their relationships to sustain one, but it makes me really angry, like the guy gets to desrve enjoying relationship and I don't. Logially, I know he will be settling too ... if there is way to just be honest that we would have prefered to be with someone different, I don't think I'd feel this way. I am nearly obsessed with this, though. It goes beyond what I think a normal person would feel. What should I do?
