Trust takes time to build. You mention you are tired of being a babysitter while she goes out. Don't you sometimes go out too? Get together with guy friends? I used to be a little resentful of my husband going out. But rather than trying to stop this, which he would have resented, I decided to GAL, go out with friends and have my husband babysit once in awhile. That's not saying I went out dating, or made up lies about what I was doing... but I try to go out with friends, bookstore, take classes, etc...
If you have a great life going you won't worry so much about what your wife is doing, and if she is in some pitiful situation of flirting with some guy on the golf course, there's a good chance she'll eventually realize how ridiculous and shallow it is and tire of the whole thing.
There is no arriving, ever. It is all a continual becoming.
