@cathy812,
I do think it's moving awfully quickly, and he may have sensed that and pulled back. You kind of got caught up in your health issues, so the timing was off. He was very nice to you about going to emergency, etc. and he kind of ended up acting like an attentive boyfriend although you were not there yet.
So.
Step back and maybe wait for contact back. Give him 2 weeks, no more. And in that time period, don't contact him. You did your bit already.
If he's interested, he'll pursue things. If not, then he won't. Live your life in the meantime. You need not sit waiting by the phone or any other such nonsense.
PS I hope you're feeling better.
