Guys..i cant tell how he feels about me:(?

ive known this guy for about 4 months now, he texts me almost every night to go to his dorm and watch movies or hang out, he visits me at my work, ive gone to a concert with him, he's met my family, and we even snuggle quite a bit but he has never kissed me. and sometimes when im with hm and his friends he's just different, he'll tease me or even be sligtly rude and says kinda grose stuff and he's obviously not afraid to rip a$$ in front of me:P lmao. then the next time, hell be all sweet and cute and kind. what s up with him? we arent technically "going out" but i just dontt understand. guys, have you ever treated a girl this way? what does this mean? is he into me or what? i have no idea how to take it.
