Dear Prudie,
I’m a single mother with two children, a son, age 13, and a daughter, age 16. My son has ADHD. For the past few summers, we have shared a vacation beach house with two other families, one who has a son the same age as mine and the other with a girl the same age as my daughter. This year we were not invited—the two friends pretended they weren't going—but I found out that they were. I asked them why we weren't included and the friend who arranged the house said that the stress of my son's impulsive hyperactivity ruined her vacation. Instead of talking to me about it, she found it easier to just exclude us. My son and I have been in therapy to work on ways to help him with his self-control. The other friend says his behavior didn't bother her, but she also didn't talk with me about it. Right now I feel that these people are no longer my friends. Should continue to be friends with them and what I should say?
