Doesn't matter when or if you date whether it makes your WAW jealous or not. It isn't for them, it is for YOU...

You don't need our permission. We aren't your parents and as far as I can tell, it seems as if you are of age...

Go for it. There are no guarantees no matter how long you wait.
Your WAW may get jealous or she may not. Who cares? Do it for you.

I wouldn't listen much to those who tell you that they "know" that their WS wouldn't get jealous. They are the same people who would have told you that their WS would never have an affair and wouldn't ever do what they are now doing. The same ones who say that their WS never changes their mind once it is made up must have forgotten that their spouse at one time promised to marry for life.. Looks like they changed their minds on that......

Make your own decisions. You will be fine either way. Don't let a lot of psycho babble sway you. It could very well be the best thing you ever did in your life. No gurantees when you date no matter how long or how short the time you wait. A person can still get hurt by another. Fear paralyzes..
