Typical anti social behaviour & a con man unfortunately.
Red flag no.1 Rushing intimacy "Apart from the fact that he started asking for my personal nr, being very open about his life, having deep conversations with me, I imagine it to be a load of made up BS"
Red flag no.2. Neediness & boundary pushing "he became quite cuddly at the end and took a long time to leave."
Red flag no.3. Baiting you with feigned caring "he brought food, was chatty, mentioning he'd like to take me out, help me out with my ad etc,"
Red flag no.4. Winning your confidence with trust,"asked a lot about my likes, dislikes, again was very cuddly at the end etc I want to point out, he was nice the whole time, talked about his previous relationship, trust and all that." You mention trust a couple of times.
Red flag no.5. Confusion if it's too good to be true it's because it usually is & they have hidden agendas. "the guy confused the heck out of me, talking about trust, Jesus, and how he'd like to get to know me. (came to see me 3 times within two weeks)"
