Dating a stripper????

i met this stripper about a month ago after getting 2 lapdances which i spent only about 20$ then she stayed and chatted with me till closing which is 4 hrs....then as i was leaving i asked for her email addy and she gave it to me and she made a comment that we do have alot in common then i left.....since then we've been emailing back and forth then finally she gave me her phone#......she always seem to ask me what i'm doing today tonight and this is on her day-off........but when i ask her to go out she'll tell me not today because i'm taking care of my bro and stuff next time we'll go out and this has been going on about 4x now she'll ask me then i'll offer and she'll say not today.......i just want to know what do you guys think is going on what's the best advice to handle these situation?????
