Working term time only, low income, how will I manage?

[Uncomfortableinmyownhome]

If my husband pushes for 50/50 custody which I think he will, I believe this will mean I can't claim UC etc
I work 30 hours a week term time. If I change jobs that will make spending time with my kids very difficult as I won't be able to collect from school or cover the holidays. He can as works from home.
My wage won't even cover my basic bills let alone anything else. I feel so trapped and don't know what to do. I'm wishing my kids lives away so that they will grow up and I can leave without the worry of their childcare etc. What do I do?

As part of my financial order it was agreed that I would be allowed that whilst it remained 50/50 I would be allowed to keep the child benefit claim (which is a gateway benefit to UC ect), but that no child maintenance would be claimed by either parent. I would definitely push for this in your order, with there being such a disparity in earnings.
