With hindsight, I think my husband might have developed feelings (perhaps even fallen in love) for a woman several years ago. If I'm right, when it started and developed would have coincided with major events in our DC life (exams, leaving for Uni) which would explain why my husband didn't leave me.
The OW more recently got married and had a baby.
Can I ask how likely it is that my husband and OW are currently treading water until such time as they decide they can be together?
I didn't think this was at all likely, as she's got married, but my counsellor told me that this means absolutely nothing and that people never fail to surprise her.
