But he has told me several times he is not ready to date. I was supportive and agreed that if he isn't ready he should hold off.
I really value his friendship but I would like to explore having something deeper when he feels ready. I want to respect his boundaries.
I don't want him to feel pressured or that I have an " agenda"?
you've got an agenda
you want more than friendship
he's not ready to date
those don't things don't really work well together
you could try something like inviting him on a hike or something else that's fairly non-dateý, but with your hopes for a relationship it seems like there are so many ways for that to go wrong
you may have to start looking for relationship material elsewhere and accept that your neighbour is your friend. full stop.
