Annoyed with friends

My husband and I are friends with another couple (his best friend) since high school and lately I'm really unsatified with our friendship. I acknowledged and tollerated the way they act for a while without ever confronting them about certain things and now I think I'm just done with them. They are flaky when we make plans to hangout and lie like say they don't feel well or don't even call or text back. I am an understanding person if they didn't feel like hanging out all they have to do is say so. He is a jealous person and is always comparing what we have. He tries to compete with us all the time it's annoying. It doesn't get to my husband but it gets to me. Anytime we go somewhere he always wants to drive so he can be in control of when we leave. Him and his wife are obsessed with money, boastful, they're know-it-all's...I could go on and on. I think I'm growing out of this friendship but he's my husband's best friend and I've grown close to his wife so I don't know what to do. It stresses my husband out when I try to talk to him about it. I don't think a discussion with them about any of this would help even if I was sensitive about it. I think I'm just going to distance myself from them.
