I wanted to get some advice on something.

I've planned a trip to Fiji for the 3 of us in Jan, and my W already said about 2 weeks ago that she wouldn't join us, but she was ok for me to take our son. I would really like her to join us fior a few reasons:

1. Our son would love to have us both there on the trip.
2. Our son needs to know that even though things havn't worked out between W and I, that he can still enjoy things with the both of us and that we can still be civil towards each other. I think this would teach him an important lesson.
3. I would like the opportunity to re-build my friendship with my W (even though she has no intentions on working on our marrigae). She might even be able to see what attracted me to her in the first place (she said it was that I made her laugh)

Obviously, she would sleep in the bed with our son, and I would sleep on the couch.

The trip is only 6 weeks away, and she asked for the divorce about 2 weeks ago. Is it too soon or is there a way I can convince her to join us ?

Thanks.
