I think a gift from your son is in good taste. If I might make a suggestion that really went over well for me with my ex (even though I wasn't DBing or wanting her back she really appreciated the gesture). First of all...no spa treatment. Too much like it's coming from you. Your son should be old enough to give him the money and let him pick. Better yet, if possible, let him do it with your wife. She can take him to the mall with the money you give him and he can shop for her. My ex thought it was very cool and appreciated the gifts more because they really came from the kids (with the help of my money). We were not close, but she made a point of telling me how much she appreciated getting to do that. I think that would put less pressure on the sitch and also would give you some brownies as the considerate guy you are. That's just my .02. Plus the kids really love doing that.
Anyway, I think we are in similar boats. Things seem to be going well, but the divorce train will not derail. I guess I need to give my situation time as do you. Hopefully the divorce train will veer off the tracks at the last moment. I wouldn't ask your wife to give it a year. Then it will make it obvious to her that you are going to hold out hope for the next year and she will never trust that you aren't just making nice to get her back. I personally think you'd have a better shot DBing after divorce than asking her to delay it. Just my humble opinion, for what it's worth.
