Apologize for jumping in without reading your whole sitch. I just have some advice on predictability.

Its the simple things that matter. Here's some examples.

1. Change your hair style out of nowhere, show no concern whether your W likes it or not.

2. Pick a simple moderately priced hobby and do it!

3. You've been running? Sign up for a race! There's age group categories, and especially with the longer ones it's sometimes just about finishing.

4. You have a son, I'm sure he likes video games, or card games, or some sport start doing it with him.

5. Call up old friends, extra points if you arrange to hang out with them. (I'm pretty sure this will drive her batty).

6. Take up an instrument(I personally did this one)

7. Go back to school.

8. Start dressing for work like you are going out for dinner. (As in dress nicer).

9. Read books? No? Start! I'm not talking relationship books either. Get a thriller, or sci-fi. Already read? Change genres.

10. Here's the best one: find something you've been wanting to do for years, quit making excuses and do it.
