He was out yesterday with with our three older kids, I had the baby and we took a nap (he had the van, I had the car). We've discussed getting another phone, but he works from home and we are together much of the time so we decided what's the point. We email/text if he's out and I'm at home. He often takes our older three out to run errands while the baby and I rest or go out and do something on our own.
It isn't that I feel unsafe, physically, sharing with him, it's emotionally, if that makes sense. He's not a good listener. I know that there are several things going on that aren't pleasant and may not make people happy. I'm working through them the best I can. I've been in contact with several people on this site, and other friends IRL.
Thanks so much for the support and concern everyone!! I will update when I have something more concrete to share.
