Ok so this guy randomly approached me in uni and asked if I had facebook (we'd never spoken before and he's not on my course and that was the first thing he asked after my name) and then added me on there. He messages me almost every day (90% of the time he starts the conversations) so I thought he really liked me, and he also asks alot of questions to do with what I find attractive, whether or not I like beards and what I look for in a partner etc. But then I found out that he had a fiance and when I asked about her he said oh she's my potential fiance it's still early days and then when I asked more he said actually she's my fiance. And when I asked why he said potential fiance when they're actually engaged he said 'I'm just joking with you'.
So anyway what does he want from me?
He also asked me stuff like what would your parents do if you were with a guy from outside your race and also whether or not I mind if the guy was younger than me (this guy is a year younger than me).
Also before approaching me I used to see him around alot and he'd stare alot and smile
UPDATE: recently he said to me 'I want to eat you', and when I asked what he meant he said 'I don't know I'm talking to a certain someone right now so my mind turns weird' or something along those lines. Then a few days later he said I'm like a sister to him and another few days later he admitted she was actually his wife and not fiance. He asks me to hang out with him almost every day after uni. He's having alot of problems with his wife and he's worried she's not interested in him because she never wants to spend time with him. I give him advice about this now when we meet but to be honest our conversations in person aren't amazing so I don't know why he wants to keep hanging out lol. Also he's told me there's no physical intimacy in his marriage.
