Why do guys play mind games? are they just to scared?

this guy ive been hanging out with told me his "friend" said i wasnt pretty or smart enough for him! but he said he stuck up for me? he also tells me things like i know you will fall in love with me in less than 3 months or that i "like him to much" then he turns it around and says things like i hope you dont Frick me over. Im so confused...does he like me, is he scared...is this is way of making me feel like hes to good for me so i dote on him? He tells me how much he likes hanging out with me and compliments me constantly then its like he gets nervous so he has to add something negative like your psycho..haha..please help me try to understand what the hecks going on!
