My wife and I have lots of fights because at parties and family occasions she flirts with all the men. And NEVER flirts with me. She says she is just being friendly. I cannot understand why she carries on doing something she knows I do not like. What should I do?
It sounds like your wife has a lot more fun at parties and family occasions than you do. I'd suggest you stay home. If her friendliness is so threatening to you she ought to go alone. There are several reasons she "carries on doing something she knows" you do not like: she likes it; it is innocent; she understands it is not a good idea for you to control how she has fun.
Perhaps, if you took your focus off your wife and relaxed a little, she would want to flirt with you. Jealousy is not very attractive. The sooner you realize that your jealousy is your problem and that it has nothing at all to do with her behavior, the sooner you will be over it.
Two things: 1. He (or she) who has the feeling (in this case jealousy) has the problem. 2. Love and control cannot coexist in the same relationship.
