Went on my first date in 16 years and I have ALOT of questions!

so I met this very beautiful woman on Facebook dating. something that I have not taken too serious in the past. I have to say, the attention and validation feelt nice. Especially after escaping an emotionally abusive and toxic marriage where my self image was destroyed daily. Over time I've gotten more confident engaging, texting, and communicating rather than just using it as an ego boost

I connected with this woman and started texting. This lead to video messages and then exchanging numbers. First night we talked for THREE HOURS! Second night I believe it was 4....and I am not a guy who likes talking on the phone.

Immediate connection. something that I have to disclose, whenever the topic children come up, it is is always somewhat awkward for me. I have two little boys, one of them is about 10 the other one will never get old. he died in an accident when he was 8. It is something I really cannot, nor do I wish to withhold.

Itturned out this woman was a therapist an actual grief counselor. She opened up to me so intimately. she was so warm and understanding of everything that I've been through the past 4 years. so by the 4th day she really wanted to see me and even though I was nervous and a little bit unprepared I figured we had already connected so much let's do it!

She was even more beautiful in person. Date went well. Same type of conversations we had before. I did let her know Inwas was nervous because this was the first date I had been on im 16 years, she assured me it was ok. she was nervous as well. We ate, had a couple of drinks and drove her home. She gives me a big hug and tells me how much of a great time she had. Then sends me a text a few minutes later saying the same thing.

I am floating the next day. I thought i had lost the ability to feel anything after my son died. After escaping my ex wife. It felt SO NICE! later that night i get a text saying how great a person i am, how special...but she FELT WE LACKED CHEMISTRY...and she did not want to lead me on. I said I was disappointed but perhaps she could tell me what I did wrong specifically so i can learn from this.

We have talked a little since then, but its done and over. What Happened!? What did I do wrong, it went from 0 to 100 then back ro 0. any advice appreciated
