Husband/father of our kids said he'd get sole custody. I fear he's right.

I'm a 22yo sahm who has no work experience whatsoever. I dropped out of high school in the 10th grade. My 26yo husband finished high school and has been working since.He recently told me that he'd get custody of our kids if we got divorced. He knows that I have no where to go if we did divorce. No money to my name since he is the sole provider for our family.He told me that he'd let me see our kids whenever and do whatever with them, but he'd fight for sole custody so he can be in control of where they are and whatnot.We aren't getting a divorce, but since he said that I fear that I need to do something just in case. I don't want to lose the kids. My husband can be vindictive about things. I honestly am not sure how he'd be if things turned out like that.I've taken care of him and our kids since day one. I've been with them 24/7, literally. Its always been in the back of my mind about what would happen if we'd divorced and since he's said that (he'd fight for sole custody) I've had this sick feeling in my stomach.It has always been my plan to get my GED when it was possible. We only have one vehicle and when my husband is home I have to take care of our kids. With our first child we lived too far for me to go take any classes or anything. We've since moved from where we were and now that we live in the city I have mentioned getting my GED, but something would come up. Our second child I breastfeed exclusively. Which is every hour and half or so and she won't take a bottle. (I'm trying to work on her taking one.)I figured I'd have to wait until either our second child was off breast milk/formula or when we could afford to put in her daycare.It's going to be hard for me to find a job even with a GED. I know that. We agreed that I would stay home until our kids were in school, but 2 kids later and I realize I don't want to wait any longer. I'd like to contribute. Even if it's not much.Now I feel like I need to get a job asap...As far as our marriage there was some lying on his end that I found out about. He's been open about it. Since finding out things have been different between us. He brought up that if I tried to divorce him to please wait until our financial and living situation was better, but that he'd get our kids. I told him I wasn't planning on it.Anyone willing to offer advice/tips please do so. I've told my husband that I am afraid of him taking our kids from me. Even though we aren't getting a divorce. At least to my knowledge. via /r/Parenting https://ift.tt/2zNgdkk
