Of course she got a tattoo. That's par for the course. I think it's written in a divorce handbook somewhere. Both of my X's got tattoos after the bomb/separation.
I'm sure that your son was feeling neglected. She was probably replying to all the ads. The time to do that, I'm sure, really "adds" up. I've used the sites a little and I personally don't find them all that great. But it probably helps to be a woman. I think I'll work on a R with one of those Russian woman. he he
Yes, I agree that this is a time of discovery for your X. She probably wants to know who she is and what she wants. All I can suggest is that you are at least still your happy, friendly, confident self when she eventually falls flat. You can decide then whether you want to help pick up the pieces.
Go on the date. Have a good time. Discover what it's like to be with someone that doesn't bear grudges against you. But, as Jo pointed out, don't sleep with anyone. Just causes problems. And last piece of advice; after going out with her, then be honest with yourself whether you can give any woman a decent chance.
In the end, it's not the years in your life that count. It's the life in your years. Abraham Lincoln
It is hard to fail, but it is worse never to have tried to succeed. Theodore Roosevelt
