I think it's normal to love someone and have times when we don't really like them very much. I know there have been plenty of times I felt that way even when we were happily married. I think one of the keys is to understand this is your issue to deal with and that you can't project it onto your spouse.
I also suspect it's all part of the cycle of emotionally healing we go through. It very well could be you telling yourself you need to spend time on and for you. Remember don't neglect yourself.
If we really want to love, we must learn how to forgive. - Mother Theresa
