My ex husband and I have been apart for 4 years. He lives with his girlfriend who he left for and I live alone. The kids spend time with us 50/50. I have been diagnosed with lung cancer - I had it a couple of years ago and had a big operation and it's returned. My treatment will mean me going to a city a 6 hour drive away for radiotherapy. I'll have to be there for 5 weeks. I can't see any option other than the kids staying with him, although I will be allowed one trip home for a weekend and the health authority will pay for my kids to come to me for one visit. But I can't relay any of this info because my ex won't take my calls or call me back when I leave a message. I really don't want to send a text - it's really difficult talking about it anyway but to send this news in a text seems, I don't know, humiliating. I could send an email but he never ever answers these either and I have no idea if he receives them.
What to do?
