Hi Sinking,
That's such a sweet gesture to remember P's birthday with a gift. Sounds as if he truly appreciated it, too. Such a nice thought.
You've mentioned a couple of times that you didn't think you could give men "what they want". Now I'm not sure exactly what that means, but I'm certainly not going to press the point. I'll only say that even if all you can offer P is your friendship, that still is a priceless gift as long as there is honesty and caring between the 2 of you. I think you are right to take things slowly and let your relationship develop naturally. Soon you may well earn each other's trust.
Much
and good luck with the family.
