I don't know whom to address my response to, so it's probably safest to post to you. Then I won't blow up and regret anything that I say.
I'm a little pi**ed off that people are seeing you as having unreasonable "demands" here. First off, I don't see you as demanding anything. Secondly, you are dealing with as much as your W is in regards to the kids. Maybe that wasn't so when they weren't in school all day or when you were on the road more, but I think it is now. You have work to contend with too.
I think your W is being very selfish in being so concerned with her needs all the time. Jeez, the past is the past. You need companionship and a normal male/female relationship. Not sure if all of these posters know how long you have been at this. I know some do.
Perhaps I am taking this too personally. I've been where you are and it just doesn't feel too good!
I know that you go out of your way to not show how you are feeling to your W or to put demands on her. What I'm seeing here is pure frustration on your part and a lot of sadness.
One thing I do agree with a couple of posters on, it that MF is a problem! He needs to stay out of the picture. I think that anytime a friend (either male or female) begins to replace a spouse as a confident or companion, the marriage suffers bigtime.
I have no advice, just support. (((((((((((ANS))))))))))))
