set up,

I've been driving my bfs car because mine has been having some trouble and he'd rather me drive his to be safe.. as I am pregnant. His sisters car has been having g similar issues and she can't drive her car.. she has never spoke to me and could barely remember my damn name when he would bring me up in conversation. He asked me if I could take her to take a pee test for a job.. I being understanding and caring about her car situation said yes.. this trio turned into several ones.. again I'm pregnant and get tired fast.. we drive around for about 5 or 6 hours. After that day she asked me to take her someone else the next day. I said yes and made it clear to him that I didn't want to be mean or come off like a bitch but I'm not going to be doing this every day and driving around to a million places.. o told him I will not be taken advantage of.. he agreed and said she understood and knew this.. so I made today my last trip.. I picked her up and took her to one place to see about buying a car.. she got denied.. I suggested she look up places that did no credit checks.. now I'm not going to go into full detail about this place but in conclusion the place was a damn scam!!! The people came up with three different prices and had us waiting for about an hour and a half.. now remember I said I was having car problems too, I decided while we waited for her papers to get back I wanted to know how much it would be for me to get a car.. he took my info and walked off without telling me anything! He came back and told us that he processed our info together and told her she could leave with a car if I signed her contract. WTF, I gave him my info to see about me I didn't give him permission to put our stuff together!! So he's ignoring me now and is adamant about her helping her with my info.. anyways long story short I felt like it was a set up maybe even on her end. Idk. I don't trust anyone. I dropped her off and immediately called my bf to tell him wth was going on. I'm yelling  and expressing my frustrations and that I was scared that they had all my info and signatures.. I didn't know what to do as I'm pulling up and I get in here and he's on the phone with his sister.. consoling her not even asking her what happened. So I get in shower and he hasn't said anything to me.. to console me or to make me feel any better about this. I get out the shower and go into the other room and he's still on the phone.. finally gets off from her and he still hasn't said anything to me. I just feel like why weren't you talking TO ME. Wtf did you call your sister for? I'm the one who was being ducked over and you have nothing to say to me.
