Just enjoy your time together for now. No pressure. No R talk. Let your H make up his own mind.
I find it is the best way to let my W to find out the truth by making her own decision. Sometimes I have to push her to make decision. In your H case, he probably is not depressed. So he can make a rational decision.
Just be his friend right now and continue your DBing. I'll keep you in my prayer.
