One-sided relationships

I am sure we all have them. Those people who are only around when either they need something or you are offering something to them. Realizing that I have a ton of acquaintances, but really just a handful of true friends. It may be too early in this process, but I really feel like "cleaning house" and dumping those folks who only drain me. Unfortunately, my husband and I don't agree on who these folks are. My yardstick is as follows: if we have not heard from you since the last time you came for a free beach vacation then you need to plan on staying in a hotel this year; if we have not been invited to your house since the last time you were at ours then I really feel no need to make you dinner again. This taking inventory may leave my shelves fairly barren!
