Mixed Signals ?

Am I getting mixed signals from a girl? I think I just might. There is this really nice, friendly beautiful women who I'm not sure if she wants me to ask her out on a date or if she just wants to be my friend. She has kissed me a few times (not on the mouth, and before your mind wanders just stop) and given me hugs but it has always been at the club. For all I know she's maybe had a few drinks and as I said she is really outgoing and friendly so maybe its just a friendly gesture. She did give me her number to hang out sometime but when I have called her she is always busy with work or school, which is understandable. I usually read way to deep into things sometimes so maybe this is just it. Then the question is if she wants to date, do I want the same? When I think about her all I can think is that she is deserving of a a man who can give her a serious relationship but I don't know if I could give her that. I could see things going on for a bit then things just coming to an end and I don't think that would be fair. Although it would be really nice to have her as a closer friend than we are now and hang out together. My heart is really divided on the subject. I also think I may have developed some feeling for someone else, so would it be fair to start something with someone if my heart isn't there? No.
