Hey TVS, glad you had great vacation, as RH said you sound emotionally weary, you have been through some tough situations for sure. If he is coming to bed each night, its gotta mean he's comfortable and not feeling pressured. Keep working on those small acts of physical contact. Having him at home is perfect to initiate that, many don't get that opportunity. Don't forget to try some eye contact.
I remember when my H dropped the bomb. He said "I miss the way you used to look at me". My DB coach said (and I have repeated myself many times here I know, but it worked for me) eye contact is a huge aphrodesiac.
I am so sad that your H continues to suffer from health problems. Unfortunately for him, the only way he can achieve some level of acceptance with that has to come from within. He obviously has lots of support from you. Am also thinking of you daily and hope you can continue to remind yourself of life's pleasures each day as we all have do. Wonderful quote. Take care dear friend.
