I want you to think of magnetism but the kind in astronomy - the planets as they orbit close then distant from each other. Sometimes when close they collide briefly, so strong the magnetism is for each other ... when there is no other force holding them back - like love/marriage.
Then their world go off into the distant orbit again with those forces too strong to resist until the next collision. It's not always about you, even him in these circumstances. The trouble with such relationships as these is that it is super risky to try & blast off from your orbit into theirs. If such a deal were to work, you'd both have to blast off into a new orbit (as you've done with email comms) that is all your own, risking that this is not more than an infatuation, a fantasy that serves "running away" from present life/loves that not so fulfilling anymore.
That said, allow me this curve ball. Many who think they are at a dead end, plan a blast off for their current spouse - 2 weeks in a no stress vacation (all-inclusive would be best). Many discover that although all the heavy baggage of the past may not be lost, certainly the magnetism of the past is rediscovered and the future is more promising.
