She said that she wasn't trying to hide anything from me and as a matter of fact, was telling me all that was going on. I'm glad we have the openness but still...
am I being too controlling?
I see it as you being wise. We need to "affair proof" our M and by expressing what you did to her...it let her know this was a problem for you. You did not accuse her of any wrong doing....and that was excellent. If you had...then her defenses would have shot up and more problems would have come crashing in.
I do believe that you may need to check up on this contacting other friend after two or three weeks have passed. If you have access to the phone bill, you could tell just how much time is spent on him.
The main thing to watch is her moods. If she is not warming up toward you and you feel she is pulling back, then you need to get to the root of the cause.
Two old platforms the WAW (who is in an EA) will use... "OM and I are just friends", and "You are controlling".
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
