Do you think he kind of likes me?

i am in high school and there is a boy there my age. we only have one cl together and we are a little different. You could say he is a "bad boy". what happens is everyday, he comes in and dosent really say hi but in like 5 min he starts trying to make me laugh and he always talks about himself and makes up these crazy dramatic stories about how he gets hur. is that because he is trying to make me pity him? anyways he has a 9th period off one of the days and he is like idk what to do. i told him i always go to the library that period because i have it off too. by coincidence he comes in- walks past me and looks over until i say his name and he sits and its really awk for the whole period because he dosent talk to me???????. then a few dayz ago he told me a story about breaking his arma and said he got into a messy fight, but told mostly everyone else it was a boxing incident. then i asked why and he said i only told people i trust. so....idk we talk in cl but its awk every other time???? how do i talk to him??
