Mom and car problem?

How should I respond to this? My mom bought me a car for my 22nd birthday because we're a one car family and my husband travels for work with our other car leaving me without a way to take our son to appointments while he's gone. She wants me to leave my husband. She demands that even though the car is in my name she gets the title to keep at her house.. My mom is the type to take things she's given me if I don't do what she wants so I'm worried if I give her my title even though it's in my name, she'd threaten to take it and sign my name to change it if I didn't come visit her an hour away enough or if she wanted me to leave him and I wouldn't.. as I said, she's the type to do that.. She wasn't going to get it for me unless I left him to begin with... but she had a change of heart suddenly as long as he doesn't drive it.. 😐 I really need some advice on this. Should I be defensive like I want to be and tell her no, I can keep it safe just as much as she can. Or should I listen to her because she bought it and give it to her even though it will cause major problems in my marriage to do so?? We're adults and can keep up with things and my husband will be PISSED if I give her my title...

*I didn't ask if I should give the car back to those of you saying I should. It's in my name and the bill of sale is filled out to me so it's not like she can take it if I don't give her the title. It's just the point that she's being demanding that she keeps it and I don't wanna give it to her. Even if I did to make her happy, it would cause a MAJOR blow up at home. So I'm in a lose/lose situation. I piss my mom off and she never helps us again. I piss my husband off and then I'm having marital issues AGAIN because of her shit.
