I don't know. I still lean towards a crossing of a line. "i look forward to seeing your smile everyday" certainly doesn't feel like "hey did you see that game? That new article in whatever magazine? Etc" that's more innocent of friendships. I've usually heard it told that if sharing of relationship woes comes up there's a line crossed or if things are said that would typically be reserved for your spouse or partner, lines have been crossed.

There are therapies out there to look into for rekindling a relationship even after betrayal. Is you husband interested in helping you work through this?
