This is tough, HB. My question to him (if you feel it's safe to ask) is if he is committed. Feelings can be nurtured to grow, as long as he is committed. If he is willing to work on it, the feeling will be there eventually. Love is a choice as you two learnt over the weekend. That's how I feel. If my H is committed, then we can both work on the feelings, love, etc.
OTOH, may be he feels too pressured with all the talk and stuff? Would it be good to take a break from all the talking about R and feelings and just be good friends for a couple of days, even with each other just doing their own watching TV or whatever to give this thing a rest for a day or two? Sometimes I feel like I am (and H is ) too stressed (with work and other stuff) and we just need a break from it all. My H is very busy/stressed with work right now so I have not talked about R at all. Just my 2 cents.
