Well, give it a little time for H to chew it over. Maybe open up contact a little more in a few more weeks.
I think I would just say that after seven years, maybe you don't love him any more. You've changed a lot--he likely has too. He is not the same person. Maybe he is better. Maybe he is not.
Have the contact so you can get a sense of whether you still do love him. If you think you could be friends, then it's worth it to see what can be kindled. If not, then you could consider moving a divorce forward, and not have doubts about it, you know?
