I know you asked for a man's point of view but I have suffered with low self esteem due to my disease as well.
For the first time in 4yrs I am in remission and I just got out of the hospital (yesterday) for an ileo reversal. I have spent a lot of time feeling like 'damaged goods' and even though I have great family and friends and an amazing boyfriend I still feel insecure. Working through this will take time for me but I am committed to my boyfriend and myself so I will make the effort.
You said you acted like a "nurse" for your husband; are there things the 2 of you can do to reconnect as a couple? There are lots of things you can do to be intimate that dont involve getting naked, and I agree with Vintageman, 3 months is a long time but not when you consider what he has been through.
Good luck! Your husband is very lucky to have you in his life!
