I know that being a woman I definitely don't think the same as a man. However, I think you would have to give your husband as much time as he needs and that when he is ready he'll talk to you about it. In the meantime trust can be rebuilt slowly with actions. IMO no amount of talking will rebuild trust, but living a changed life daily as you said you've been doing should go a long way towards it and I guess that no one could put their finger on exactly when things will be 'ok' again.
I do think that if you both work on yourselves in terms of becoming more Christlike and more godly, the process *may* be a little quicker. A lady in my family was given some advice when she and her husband were getting over an affair...she was told that once they'd decided to work on things to put it behind her and never bring the matter up again because in doing that they would end up focusing on the very thing they were trying to put behind them. It's taken a long time, but their marriage is now better than it's ever been, and by this lady being quiet about the past, and working on showing her husband the love of Christ instead of preaching to him and trying to convince him with words, he has also now become a committed Christian (not saying that your husband isn't...just trying to show that actions speak a lot louder than words).
Paul sums love up very well when he talks about it in 1 Corinthians 13...
4 Love suffers long and is kind; love does not envy; love does not parade itself, is not puffed up;
5 does not behave rudely, does not seek its own, is not provoked, thinks no evil;
6 does not rejoice in iniquity, but rejoices in the truth;
7 bears all things, believes all things, hopes all things, endures all things.
8 Love never fails.
Hang in there.
Praying for you...
