Roz,
I am so sorry when things like this happen. Sometimes people are too afraid to work at it. So you need a little more help with things than you did "before." So what? I am sure that he also had "needs" that
you attended to.
Where you want to go from here is up to you. You can take care of yourself even if he is not there. Get some counseling, even alone if necessary. It may not change anything with your partner, but I am sure you will feel better. (We all can use that from time to time.)
Know you have a lot of people here who do care about you.
Mike
