Help please!! boyfriends mom?

OK, i have been dating my boyfriend for about a year and a half, im 16, he is 18. so he is a legal adult!! but his mom is a crazy person! she sent me a text message telling me how i need to do everything they say and stuff in order to be with her son, well i got sort of pissed and sent her one back telling her she needs to back off of him! the has to know where he is 24/7 and what he is doing and stuff well she says in their family your not an adult until you have a job that pays more than 7 dollars an hour and you can support your self. but, she has NO job, and is living in her parents house either rent free, or is only paying what she wants. so im like what the hell?? hyprocrite much?? seriously! and for the past 3 weeks she wont let him see me at all unless i go over there and talk to her, and i know exactly what she is going to say so i think this is rediculious. so i have been telling my boyfriend that he needs to stand up for him self and me, i i guess i just have it stuck in my mind, that if someone really loves you that they wont let anything keep them away from the one that they loved, and he has not done anything to see me. he fights with his mom, but his mom just takes things away from him like his car, and his phone.. so finally, im agreeing to go over there, im going over there tomorrow to fix this because he wont and my mom wants to go. but i dont know if its the right thing to do. my mom is going to find out why all this is happening and stuff but i feel like i should not have to fix this and my mom thinks that she is being rediculious!. but i love him and could not stand to loose him... any advise?? its not like he is not going to school, or does not have a job! its like as soon as he does everything she wants, she is still not happy and still finds reasons to take him away from me (this is not the first time this has happened) help.. ugg :(
