Inlaws...

So, my father in law gave my husband an ultimatum...we either have to live beside of them or my husband has to leave me...we just got married on May 16th...my husband has not left but I'm not sure I'm ever going to able to forgive my father in law for even saying that. I'm a Christian and I know it's wrong to hold grudges but that's just not okay...right?! Or am I the one being difficult?!
