What to do about my feelings towards my husband

Hi there!

I’m working on the relationship I have with my husband. I feel a lot of resentment, frustration and betrayal. I know I have manuals for him but don’t know what to do with them and or all of the above to be honest. Should I feel these emotions first and then try and change my thoughts about him? I feel like I want peace and acceptance but when does it become settling? I guess what do I do once I arrive at these emotions and still question if he’s right for me?
