Some Ex's can be quite hostile after divorce or use the kids as weapons or leverage out of anger or revenge. This can be the most extremely painful and stressful time. Don't wait or delay. Get an application to court as soon as you can. You'll have to try mediation first but it's not likely to get past the first session in these circumstances. This is not just for you but for the kids too - they need love and stability. Kids usually accept quite quickly that their parents are living in separate places and want to see both of them and not have too long a gap. The law is on your side here. The children have a right to regular and significant time with both their parents.
