No. I would not do it. What message does that send to her? That you are "crazy" [what woman would go up to her H's mistress and say, 'Hi! I'm his wife!"] No, honey, I do not think you are crazy, but how would that come off to ow?
Hold your impulse to put yourself in her face. She knows you exist. Remember, he is NOT married to her...and she knows it.
You do not act friendly towards ow...do nothing at all. She does not deserve your pleasantries or thoughts. Your in laws are pretending because they don't know what else to do...he is their son/brother, etc. and they are going to be supportive of him. My in laws stopped contacting me, too. It is common.
Not to mention, you do not want your daughter to see you introducing yourself to the ow. You do not have to be her friend or get along with her. Ignore. Read some affirmations when he drops her off tonight and say nothing. Hugs.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
