Blind date did I make the mistake because I am too vulnerable now?

I met a decent guy online and we met for drinks and appetizer's. He is in his mid 40's and never married and I am in my late 30's and just haven't settled. I wonder why he never married, and he said he likes being alone but not forever and just never got married yet. He just had a 7month relationship and was talking about her alot- she left him. So red flag - he is not over her?We had a nice time and closed down the place. I am in a vulnerable state now in my life for various reasons - no full time job economy etc...so I made a mistake and feel awful. How can I ever settle down? He ended up pursuing me to let him back to my apartment and he slept over. Now, this morning hours later- I see he is online. Pig huh? Is it me or is it him? I am not a easy woman- I feel terrible..the wine got me. I told him 4 time "I am not like this- I never do this" he said honey don't worry. When he left he said by honey we will talk soon. Did I ruin this? Should I text him? I feel terrible!
