Open Question: would i be wrong? okay well...what would you do?

Me and my mother are joining a business and therefore we would be owning our own part of it, it is in the network marketing field. I don't have all the money to start up on my own right now although I will have it in a couple weeks. My boyfriend is signed up under the same company but my mother was in before him and tole me about it first. My boyfriend who has lots of experience in this field and is very educated and would make a GREAT sponsor said will give me the money if I sign up under him. In network marketing you make your money and more money that way. My mom is very computer illiterate, she's very lazy, and wants me to learn everything first, and I'd end up doing all of the foot work, and probably slowing my progress because of it... I don't even know if she will put as much time in it as I will. My boyfriend has lots of experience and would be able to teach me a lot and I would prosper much more from working with him. I'm having a guilty conscience because she NEEDS my help but I don't want to end up doing EVERYTHING!!! But she did tell me about it first and she absolutely can loan me the money to start up, she just doesn't want to! The faster I start up the better, but she and I live together, I just moved back in with her a week ago. I mean I love my mother, it's mother's day time, but she is trying to beat me at the game and doesn't want to help me get started and I could make her much more money if she'd just help me start now. Do I let my boyfriend help me out and we support each other or do I go under my mother and pull all the weight? I pretty much know the business and I taught her about everything she knows and I myself haven't even opened my business yet. I'm confused... Is blood really thicker than water? Or is it just the way business is? HELP!!! My head is about to EXPLODE! FYI: me and my mom haven't had the best relationship, its getting better, but if she get mad I could move out.
