hmmmm sorry I've been there. I was a SAHM when my kids were small and DH had long hours too. I'm sure you have heard every kind of advice but hopefully you and he can work out your schedules. Even if it's only one weekday that he can make time but then you have Friday and the weekends, you can make that work. But I know it sucks.
Thanks for the knowing what it feels like. I actually read his time wrong (he uses military time and apparently I wasn't thinking clearly) but I was able to get my first workout in. I had to do 10 min. I ran 2 min over and my pace was 11:44. Not bad for only able to get a run in on fridays most times. i did have to laugh at what i probably looked like but at least I was moving.
