Is it normal suspecting my friend is a wolf in sheep clothing

My friend is depressed due to getting dumped by a woman he was talking to romantically on the internet.
My mother have always been going on about how I should date him he's the only man for me so I decided fine. He's always wanted to date me anyways. The same week his "girlfriend" conviniently dumped him.

I showed a vague interest. It was plenty for him to start going on about us being a couple. I told him i'm not sure how I feel until he's visited since I haven't seen him in years. He still didnt slow down.
He wanted to exchange nudes one evening and I refused. He still sent me nudes. It was at that point I began suspecting he was only after sex. He was disappointed I wouldnt video chat nude too. My mother told me its no big deal I should get over it so I tried to and it seemed to be going well.

When he came to visit he kept referring to me as a friend.
I confronted him the next day and he said he's still so upset over his "ex" but that its a good thing he has a friend like me to get him through it. I was like you said all those things to me when you didnt even mean it ?! Like wtf ? He just played victim and got distant and he blamed everyone else saying someone should've told him to slow down since he just got dumped, when that is what I literally tried to ??? But then he seemed so over her and I believed that because they never met.

Now I dont know if he does this in rotation with all his female friends.. He only has female friends which he says is because he's not like other guys / better and more sensitive than them...
He claims all women he's had flings with have acted in extreme and dramatic ways and he's always the innocent victim... In all his many stories of failed relationships he has never done a thing wrong...
Him and his "ex" still have each others names in their bios. What if he started hitting on me lying about her having dumped him to try to get sex ?? I am wondering if all along hes been a wolf in sheep clothing ://
