Just used google and what do you know, there is a whole list on another part of this site:

It's impossible for someone to diagnose you through the internet. It might even be more useful to focus on the actual behaviors that are bothering you or others. Like if you talked to a therapist they would ask you what scenarios keep playing out, how you feel about them... just to have a more well rounded and balanced picture to go on, where they could say "THIS is the crux of it, and doing THIS would help"... They might recommend counselling alone or as a couple.

Sorry to hear you are having marriage troubles--good luck.
