Does your husband know about your "fling"? Have you told him? If I were only separated (as opposed to divorced) that would be a hard thing to just overlook. Maybe you're both better off taking this time for yourselves. Do you really want to go back to the way things were with your husband? Because they may not change. It's tough to miss someone you care about, but staying in something that isn't good for us is hard as well. Hugs to you.
