Personally, I think this man has abusive tendencies. The mean comments he made to you and other responses, which you remember many of them quite clearly, is not the behavior of a man that adores you and wants to impress you. Even if he was upset or having a bad day, this kind of conduct is simply unacceptable. You deserve to be treated better than that at all times. Everyone deserves that in fact. Apparently, he is comfortable with focusing his negative emotions towards you in a cruel way. I find that to be a dangerous trend especially since the relationship is still relatively new.

When he expressed to you that he only wants a physical relationship initially and always "needs a relationship", that is not very flattering towards you. It comes off to me that he wants to use you for his own needs and that is his primary concern. Again, that is simply demeaning.

The last message to you seems manipulative to me. He has tuned in to what you are looking for and will lure you in again with compliments and promises that he wants to give you what you seek. I believe there is a strong likelihood that he will revert back to his abusive ways once he has won you back. My opinion is that his actions thus far hint at an abusive nature. You can either ignore him completely or make it clear to him that you want him to leave you alone and warn him you will take the necessary steps to enforce that if he does not comply - the choice is yours. I agree with you that he will not change - at least not until he recognizes his harmful behaviors and takes steps to correct them. There are way too many red flags here in my opinion. A decent man would not do these kinds of things.
