If he is truly "poly" then you are not "the" one, you are "a" one. If he just needs to be with other women for sex, then maybe you are "the" one but you probably shouldn't think that it will change once you get married. If you can't handle this in your relationship for the duration, then don't prolong the inevitable. 10 months is not a very long time; you can still cut your losses and find someone to be with whose vision of what a relationship should look like is more like your own vision of what a relationship should look like.
