how do I love my husband again? 😣

I want this feeling of not wanting to be with my husband anymore to go away. We've been married 4 years and I feel sad that I feel this way but I can't help it 😢 now that he's doing better and being the man me and our son need him to be I still feel like something isn't right I still feel unhappy and I feel bad about it. Maybe I subconsciously resent him because of all of the things he put me through and I only forced myself to believe i forgave him and I was happy again or maybe I'm just stressed because of the newborn.. idk but I hate him and I want to love him again. Every thing he does bothers me and makes me hate him more! What do I do ? 😭
