Apologies in advance that this is so long . . . It may be so long that no one reads it, but I am just posting to get it off my chest because I am so bad at this and so frustrated thinking about it I woke up and can't go back to sleep

. I feel better just knowing my post is floating around in the vicinity of good advice
So, I feel like the dynamic of a couple is largely none of my beeswax, but in a semi(un)professional context I am getting very frustrated with a controlling husband machoing it up for his wife. I tutor as a side job, and in this case I responded to an ad that it turns out this guy posted on his wife's behalf. I have dealt with guys trying to make a show of overprotectiveness/hardassiness before (e.g., trying to sublet for 1 mo from a woman whose boyfriend interrogated me for the better part of an hour and demanded everything short of a urine sample), but you don't always know what you are getting into.
Anyway, basically he is one of those guys who has decided his wife is not capable of her own business dealings and is going to step in and flex his guns and do the money side of things for her. I am pretty bad at negotiating (my own problem, but I don't get my bf to do it for me!), and long and short when I went to meet her he stuck around for the money bit and I am working for about 20% less than we had initially discussed and about 60% of my normal rate (I had already offered a huge discount because I am still trying to get on my feet in a new city).
The agreement we came to was that if they want a deal, they meet me at a place that is convenient for me. Why anyone would want to bother with the price of gas and an SUV is beyond me. Well, in the next breath while talking about possible meeting places I stupidly mention that my bf works midway between us and I pick him up anyway. THEN even more stupidly, I agree to meet there at a time that is nowhere near when he gets off work!
My own fault, but when I meet my student tomorrow, I want to tell her it's not working out for me and here is the new time and place. As we discussed it, they are meeting me at my convenience in order to pay me less. The specifics were a tentative arrangement for the first few meetings. But given we talked about one right after the other and the husband's personality, I have the feeling he is going to really push against it. He has already seen that I am not a strong negotiator.
The woman herself is very nice, but her husband clearly wears the pants. It also turns out she is pregnant, although she's not yet showing, so hubby carries her books in and out of our meeting place. Cynically I feel like this is part excuse to be there for any logistical talks. He is pushy to begin with and already seems to regret the arrangement we have -- yesterday he offered me an extra $3 if I would go to their house. They live cross town and we all know enough about GAS. That doesn't cover it, and besides his whole shtik to begin with was that they just couldn't afford to pay me a dollar more. Her school is actually subsidizing most of it, so they are barely paying anything to begin with (AND I had to send in a stack of documentation and will have to fill out time sheets, have taxes withheld, and wait a month for my first paycheck).
The woman would readily agree to my terms, but the husband will not want to give. They both have completely flexible schedules, as they have already told me many times. So the downside for the husband is that he would have to drive an extra 10 or 15 minutes. As far as I know, he actually does not have anything to do for the summer.
The downside for me in the current situation is that I absolutely have to drive my bf to work obscenely early in the a.m. and that he cannot use the car to take a break, run errands, or get off early. We are talking waking up around 2:30 AM and bf usually works 12-14 hours, so there are days when he is just tired out of his mind or really wants to come home early because we have had very little time together.
. . . What is a polite, firm way to tell these people I want to work something else out? Should I bring up the personal stuff, leave it, give my real reasons, or pretend it's totally not an option? Maybe if I say my bf REFUSES to let me have the car EVER the husband will understand from one controlling d*** to another? If he just says NO, should I also say NO? I doubt they are able to find a replacement at this point, and I don't think I am really putting them out.
Obviously, I was aware of the negatives for me going into this. But I guess if I were being paid decently, I would feel like things were picking up and with a couple more students I could get some ratty old car to see me through the year.
I don't absolutely need the money, but I don't want to rely on my bf, and while we are comfortable he does pass up a lot of things. He might be upset if I just let the job go (if it came down to an unlikely impasse), but on the other hand the transportation/scheduling issue is also stress we don't need. I will talk to him about this on the weekend but can't today because he crashed right after work.
It is the middle of the night for me, and I know I am in real mountains-out-of-molehills mood. I am just upset about this because I am at a point where I have been rethinking a lot of major things, so this seems to signify more than the literal. I need to establish myself in a new place, so I am trying to do what I know, but I also can't be a knockabout all through my 20s. I really want to get out of the freelancing business, especially since, as you can see, I don't have the personality for it (although I haven't had real issues, just stress, with the usual parents/kids or clients in my other (currently inactive) side job).
TIA for any thoughts, and if you managed to read through my post! I think I can go to bed now . . .
