Is it odd?

My soon to be ex MIL called me today after about two months after I filed for divorce and put a restraining order on my ex and kept asking me questions..not how I've been or anything like that. More like if the restraining order went through or the divorce...(my ex never signed the papers and never responded in court so I have to go do my default papers) I was kinda caught off guard and even shocked she called me and confused. She also kept saying how he was over the marriage and he was not gonna contact me and he knows it's over for good. Am I the only that thinks this is weird?
