Please answer???? 10 points for best answer!!?

Ok so I've been told countless times by one of his friends that he likes me an blah blah blah and he told my other friend that rob was talking about my to him all the time. This has been going on since 8th grade . I'm in 9th now but the thing is when this guy tells me stuff like this I kinda don't believe It because he says it alot and I can't believe that rob would let it go on. But on the other hand when ever he gets on my friend Andreas nerves she always pulls out shut up rob you like Jessica ( me) and he doesn't say anything. And I went to a 15 the other day and he was one of the guys in her court thing and when they had a dance circle rob kept trying to push me in the middle and he knows I'm ticklish so he kept tickling me alot to go in the center and dance and he even told me if I went that he would go with me. I turned him down cause I can't dance but one time while he was trying to coax me into dancing out in the middle his arms were around me and he wasn't tickling. They were just there like he was cuddling me. The other thing that worries me is that he was tickling other girls too tho but he didn't cuddle them like he did to me.. Idk am I wrong?? Please please help!!!z
