I see this kind of thing much too often. Guys confuse the manipulation inherent in a person's job as something more than what it is. I know not all dancers are the same, but this woman flirts with guys for money. The more she pays attention to you, the more you pay for her dancing, the more you come back to the club, etc. She calls you to keep you on the hook. And she spends time with you in the club because, as you said, it has been dead in there and you are her meal ticket right now. I am sure if you look around, you would notice that other girls are doing similar things to other guys at the club.
Reality - you see her when you go to the club where she dances. You never see her outside the club (in the real world). You don't have her phone number. You bring her gifts and help subsidize her salary. You don't have a relationship. There is no anniversary date. Period.
Since you said you have low self-esteem, you are probably hoping there is something real between the two of you, but there isn't. She is using that low self-esteem to manipulate you. Even if she isn't doing it on purpose, she is doing it. This isn't real.
Do yourself a favor and concentrate on liking yourself. Get involved in other activities and meet real people in the real world.
Good luck.
p.s. - Just to make it clear, there is NO possibility there. Don't even think about it.
