If he asks if im single & other ?s is he interested?!?

OK so there's this Guy I work w who is friends w a Guy I made out w...the Guy I made out was being a douche and told me one of his friends want my number and I told him off and told him I'm not some pass around so we don't talk anymore. Well the Guy I work w is checking me out a lil lately and I wanna know if its him who wants my number! Today I was waiting on my ride home and he sat next to me smoking and didn't say a word. He seems shy so after he started a second cig I told him they r bad for him.lol We ended up chatting a bunch and he asked if I'm single and how old my daughters are and how old I am. He asked if I work tomorrow and I don't. Then he paused like he wanted to say something but my ride showed up!!! Do you guys think ts him? Or that he may be interested in me?:)
