Happily married for 12 yrs. Never any threat of infidelity. Great marriage. Just found out recently that wife ex boyfriend emails her now every day. Increasing contact each day. Does not sound like they talk. Highly unlikely they have seen each other. She responds but never initiates. Very friendly tone.. not seeing each other. Wife talks freely and often about me.. guy does not mention wife. Likes to talk about himself incl workouts etc. I maintain great and intimate relationship with wife. She does not mention this contact although I never confronted. Should I be worried. Ex married with kids by the way

It doesn't sound like you have anything to worry about. If she starts suspicious behavior and red flags then you might have to start worrying.

dr paranoid...
It sounds like you are spying on your wife.
You haven't confronted her? but yet you know all these things?
And nothing that you have found out makes you think anything strange is going on?
She talks to him about you a lot and they are just conversing normally, how do you know all this, if she hasn't told you?:confused:

The question in my mind is - why are you worried?

It all sounds perfectly innocent to me, but why did you feel the need to check her emails?

If she talks freely to him about you, why don't you talk freely to her about him?

It's been 12 years - talk to her.
