I'm 31 and my partner is 35 we have been together 4 months. Very soon after we started dating his mother has been diagnosed with terminal cancer. She is responding well to treatment. However out of nowhere he told me he doesn't want to be with me anymore. That he needs to deal with it alone. He doesn't have much support other than me. I have been there for him from the beginning and am aware of how difficult it will be as the illness progresses. I've told him I am ready to be there for it all but he's said he won't put me through it. He has very little support otherwise and I desperately want to support him in this. What should I do?
