This zone thing is fortunately more of a younger person's deal. Mid 40s, here - so not a problem.
For example, my very lovely former coworker just had a baby 2 months ago. I made (CW) BBQ for her and her husband and ran it over tonight to their house. I know how it is with having kids, and that first 6 months new parents don't really leave the house. So I made dinner.
Anyhow, I'd be lying if I said I'm not attracted to her but we really are just friends. I have no idea how she feels about me, and I'm trying to find out since I'm married. We're both married. Point is, I really don't have many friends so I'm happy that she's my friend and vice versa. Today was the best day because I did something nice for her and her dude with no strings attached.
Be happy someone is happy with you in their life on any level.
Yeah fr young people be like "I'm so angsty because I love my friends and desire a deep personal connection with them" that's what friends are for you fools!
