You don't need to right now..not being flippant. I just want to dissuade you of the notion she will care. Not now but perhaps later.
Allow her this time, it pays dividends later.
Your doing pretty good, good grasp, be a great dad...strive to be better than great.
I do have two questions for you.
First, most important, is your name on your son's birth certificate? As long as it is, then while it pays to be concerned about her actions, you do not need to be paranoid. And in this case...paranoia is nothing more than a heightened sense of awareness.
Second, What are you working on improving in yourself? No offense, I am sure you're a great guy and catch, but if you take a really hard look at yourself and your impact on your marriage, what could you have done better, what are you not proud of?
Fix that sh it in yourself, see the need to address it and fix it. Let it be for real let it be real change.
She comes around and sees that in you, you look even better.
My personal thoughts about the POS OM. (piece of sh it) (other man).
In my case, my wife needed to 'fix' somthing/someone since she couldn't 'fix' herself, she tried to 'fix' this guy. Anti-social, depressed, stalker, loser. The only one who truely understood her...go figure. ; ).
Do not let Amy40's number of posts fool you into thinking she is a newbie. Her insights come from experience you never want to live through.
