Have just found out that my DH has invited his mother to stay over New Year, so that she doesn't have to be on her own. She is already staying nine days over Christmas for most of which I will be either biting my tongue or hiding in bedroom to avoid all-out war. MIL is obsessed with DH, besotted to the point that I find it creepy. DH is 50 and has grownup daughters yet MIL is still re-telling the tales of his O levels, schooldays, what he did as a toddler, you name it.
I have carefully, politely, and delicately explained to DH that if MIL stays longer than the original agreed nine days, I am moving out to hotel and going to the party without him. OK, what actually happened is that I said "oh f*" and the put the phone down on him, but you get the idea. Am I being a complete cow or is this reasonable?
