Help me. I don't know what to do. I live with my SO and our 9 year son. The ex-wife and her adult children keep calling and making excuses to come over to our house. Excuses, such as favors, always flat tires, brake work, etc. When they come over, they never come to the house alone, it's always in a group and they try to intimidate me by outnumbering me.

My SO allows this and he feels that they could do no wrong.

What should I do?
