My wife and I were married June 10, 2000. She runs a daycare out of the home, and one set of parents are divorced. One evening last fall she said that he, the divorced father, had asked her out to dinner and that she decided to stay home and have dinner with me. I asked her if she was trying to make me jealous of him and she said yes, but couldn't give me a reason why. I truly believe she was trying to make jealous of him, and that nothing was happening between them. Anyways, a couple months later her and a friend were talking about him, and how he looked in a swimsuit, they stopped talking as I entered the room and said that it was just girl talk. Later that night I asked her if she had any feelings for this man, and she said no, but she had had a crush on him earlier when she was trying to make me jealous. This all happened the fall of 2000. After the last conversation we had about it, everything was fine and we have been our normal selves enjoying our new baby, as of April 14th, until recently. A couple weeks ago she started being ALOT more agitated with me, for no apparent reason, that I can tell. Last week I came downstairs and she was flirting with him again, which normally doesn't bother me as this is the way my wife has always been. The thing that is bothering me is, that ever since that morning, if I am home and she see's that it is his car dropping the kids off she will immediatly make herself unseen by him, i.e. going upstairs or to the kitchen until he leaves. The other thing that is bothering me is that, last night I came home from work and walked into the house, him and my wife were sitting at the table talking and as soon as I walked in the house he got up and left with his boys. This last week they have been avoiding being together around me, which is very much not my wife. The reason that I am suspecting something is, that it is normal for her to openly flirt, which honestly doesn't bother me in the least. We actually joke about it. Do you think that I should take concern to this change? I don't want to make a big deal out of it, as I feel that would do more damage than good. Any advice would be helpful.
