Two options:
-
the nothing-ventured-nothing-gained approach: suggest that "get together" - by text, unless you are really, really brave and dial the number instead.
-
wait and see; if it's meant to be, you are bound to bump into each other, etc .... etc ....
It all depends on how you are feeling. If any sort of rejection would be too much, go for option 2. If in the light of day and being totally sober, you think your fellow texter would enhance your life, why not take a more active role?
I know what I'd do but I'd sure wish I had the nerve to pick up the phone . Mind you, even imagining it, would make me light-headed (easily pleased, here!)
