Does he really like her? easy ten points?

my crush carpools with a girl. she was telling quite a few ppl that she wanted him to ask her to homecoming, but i never really saw them talk at all. he flirted with me alot on tuesday, then later that day he asked her out after she had a volleyball game (she lost btw, idk if tht matters) and he stands by her in the morning b4 school, but they nvr really talk, and the next day she told everyone that he asked her and he didnt say anything at all. and on her facebook her status is single, and shes on alot. and this morning, he put his hand on her back, and said hey she said hey and they said sooo and then they both started talking to other ppl. i c him at her locker now, talking sometimes. do you think he likes her? (they dont sit together at lunch) my bff thinks he feels bad or his mom made him. what do you think? thanks:)
