MIL Asked that I don't answer her video calls from now on

My (M38) Mother in-law is a mean woman who always assumes the worst in people, And lately due to pandemic, My wife, the kids, and I have decided to minimize our visits and trips to mall/parks/coffee shops, We do not go out unless necessary.

Wife (doctor) Was working, She left her laptop in the house, We share this laptop, Mother in law decided to call us on skype, I answered her call, greeted her, Asked her how she was doing, And her replies were pretty short, And sounded like she was expecting my wife to answer and not me.

She started asking if we went out on mother's day, I told her no, She asked If "I was sure I didn't go over to my mom's and celebrate mother's day there", My answer was pretty clear, I told her no, We stayed home and didn't go out, Didn't see or talk to anyway. Not even mom.

She then proceeded to tell me about her son's birthday that happened to be yesterday and that everybody was there (cause she forced them to come, It's her precious little boy's birthday!) She wanted to know why my wife and I didn't come, I was taken aback, I honestly did not know it was his birthday, And I don't care, The guy is an asshole, He works in military and is so full of himself, And has always been totally disrespectful towards me (not sure why) So for her to expect me to be there on this asshole's birthday and pretend that I like him is a big no!!!(The next part will tell you why)

She said that her son thinks his relationship with me was "okay" then, Now he dispises me!.

The fact that she had the guts to say this to me is unbelieveble, But she gave me the "I'm just a messanger" look, I made up an excuse trying to wrap up the call before she hung up she told me that next time I see her incoming video call I just have to ignore it and let someone else answer, cause she only wants to talk to the kids or my wife.

When The call ended, I almost cried, God What she and her son said about me is… I can't describe how I'm feeling right now, I guess I'll just let my wife handle the "video calls" from now on, I don't want anything to do with her or her asshole son anymore.
