I have no idea.  I totally wish you both the very best.

What does SHE like to do?  Start with making your partner be the focus.  Let her respond in kind.  Giving will be a real testament to how serious you are in spending the rest of your lives together because if you cannot do that, you don't have much of a chance at happy.

Good luck.

Have a shtup.
