Oh deli, that makes me smile!!! A really big, happy smile. Things you should be proud for:
1: that you re-checked and confirmed you two meeting-that you didnt give in to the negative thoughts swirling around about how he doesnt really care...etc
2: that you feel proud of yourself!!! That is HUGE! You are showing self-worth, and its awesome to see
3: you reached out. To us, pdoc, AND austin-T
4: you talked to A about really difficult stuff- talking about sex is SO hard. I cant do it and ive been with my T for over 3 years

I think (and had hoped) that his response was really great. He was understanding, sympathetic and rational with you about what you should expect of yourself. I didnt get the feeling that he will disappear from your life. Im really sorry his cancer spread, that is scary. You did wonderful, so just let that sit with you!
