Personally, I don't see why, of all things, your husband would get in the way of doing what might or might not be right for you...

I hope you don't feel forced to maintain the relationship for any reason, and that you maintain it because it's what YOU want to do/feel is the right thing to do

Remember you are your own person with and without those around you: you are strong

P.S. Maybe I misread you, but it seems like things are becoming... bearable now?
