My vote is he was fun, he lifted your mood, reminded you that you ARE attractive, desirable,etc. So, "Yay" for that.
That being said, you have had that fun and validation. I would say the rest of the things you have learned about his attitude would indicate he is clearly not 'relationship' material. But then you already know that based on what you have written.
So, take care in the future to always be protected, and do not commit yourself any deeper so you don't have to deal with the drama of that ending, which it seems it would, eventually.
