Just from the beginning of the post. (I read it whole, but looking for things to ilustrate to you.)
So he saw no issue to be deceiving a woman he was with, blaming things on her and her fatique/mental health (you sure she was not just tired of his drama & lies?)
He sees it so fit to immediately get a new woman, who is even with someone already.
Then he is all about being hard to get, and talking about singletness...
Only to get you to bed, and he would not act as a caring partner either, because no kisses / nothing of your needs, all about him and sex when HE feels like it.
Then talks about how he is no longer in love, which very much sounds he was in one only as long as it was good to get you to bed. Talk is cheap.
Then he contacts someone else, & bullshits about how accidental it was / how he juust ran into her... and is soo concerned... about someone who is meant to have moved on long ago.
Then he gets bored & moves on back to you.
On, and on, and on....
Yet you say he is not an asshole?
This lying, cheating, never committing to one woman, thinking he is so irresistible, & just hurting everybody... very much spells an asshole to me.
Scared of intimacy?
He would be committed. To one woman. Struggling with the relation, but not with being nice to her / communication / decency & honesty about other things. This is the opposite of scared of intimacy. This guy is choosy how to treat everyone to inflict max damage he can. Which is power moves, not fear.
