Is it possible to really dislike your spouse to the point of hate??

can. 100% if you're not enough of yourself in the marriage, you'll start to resent your partner for it. (assuming that is the relationship dynamic). There are some couples where they really 2 become 1 lol. So it quite depends on your relationship dynamic. Or like, you or your partner cheat on each other etc. I guess the question was pretty vague to begin with, so the answers could be all over the place and not what you're looking for. BUt yeah, barring any extreme actions on either partner, it still is possible!
