No I assumed he had mental issues because of the things he said and the way he talked to me and the way he would plan something down to the hour and then either cancel or ignore me. The only reason why I let him do it three times was because I really liked him. And I would have totally cut my losses the first time if he didn't keep leading me on, he would say things to me like "Wow you're the most beautiful girl I've ever seen." Then cancel on our date and he would confuse me with what he said versus his actions. I don't feel desperation for him, I just kept giving him a chance because I'm actually nice and really liked him. Plus I thought it was his mental issues because he has PTSD which I'm very familiar with so instead of just assuming things I gave him the benefit of the doubt and wondered if I needed to be extra patient with him because of his PTSD.
And the only reason why I said I liked everything about him was because I was trying to let him know that it wasn't just physical for me, I actually liked him, not just for his good looks.

It would be desperation if he said hey I'm not interested, and I kept trying. But he literally kept leading me on, so I was very confused. I really did attribute his behavior to his PTSD, but maybe he was just a plain old jerk.

My question was just "what would make a guy lead a girl on" since obviously he wasn't interested but kept acting like he was. I don't still want him, I'm totally done with it.
