I'm gonna call shenanigans here and say J will push for sex and currently wants a relationship with this woman.
I have been interacted with him on this board for a year and a half and am a good judge of character.
He will not love her and leave her he is too good of guy.
I am more concerned that he is forcing himself to like her even though he admits she is not his typical type.
That's what I am concerned about. he is willing to talk himself into wanting something he doesn't to get laid. I imagine a lot of guys are doing that with her, then eventually they are like "I do not want an R with her, I rushed into it"
And you know what a person of good character would do in this sitch? Be completely honest with themselves and the other person. That's what a good guy does. Not convincing himself he wants an R to get laid and then stay with her because he doesn't want to hurt her. That isn't anymore respectful.
