Hello starryprince: Congratulations on finding someone special!

I don't know as I have much of anything useful to offer here.

It's been many years since the Skeezyks was involved with fostering new relationships.

My thinking with regard to this is to share, with your new friend, what you are feeling.
Of course, you don't want to dump it on her all at once. You could possibly scare her off.

But just a bit at a time, share with her what is in your heart.

This may not only help you to feel better... but it will give her permission to share her inner feelings as well & possibly draw the two of you closer.

The other alternative is, of course, if you see a therapist, talk this over with that person as well. (I'm sure you already know that.)
There are Buddhist practices I could share with you that address this sort of thing as well. However, I'll presume this is probably not something you'd be that interested in. So I won't go into that. These are the sum-total of my suggestions. I wish you both well...
