Boundaries???

How do I set boundaries with my mil? She wants to see my son every week but I am sorry I just can’t do it I can’t stand her. Although she is a nice lady, she has done so much stuff to annoy and disrespect me after my son was born. She texts me instead of my husband asking when she can come or when we can go over and it’s really annoying. I can’t forgive her for how she has made me feel after my son was born so I have a little hatred towards her and hate seeing her.
