Grassgreener,

first let me say the age old adage......

the grass isn't always greener.......

but I'm not in your shoes.

To answer your questions.

No, it don't matter at this point when you divorce. It sounds like you've already got the minimum requirement to get some of his retirement.

Next, alimony or spousal support will depend on which state you file in and how good your attorney is.

Does your spouse know you want a divoce yet?

Good luck
