I can see where you're coming from if this person is always doing things like this. However, she probably wasn't throwing her own shower. It usually is left up to the mom, sister, best-friend of the expecting mom. THat person is probably the one who didn't invite you. (I love the It's My Birthday story!)
I agree that it's silly to invite people who live very far away- especially if you never talk to them.
I would wonder though, is it DH relatives, or yours? I wouldn't want to embarass him by ignoring it altogether, if they are "his people" even if they were rude. If they were my relatives, different story-maybe.
Nowadays companies (like Target, for example) tell you to include the registry info with the invite. I am torn on this. I think it depends. I purposely asked my sister not to send registry info to people unless they asked for it. SHe invited people who live out of state, even though we knew they wouldn't make it. I didn't want to seem like I just wanted a gift. They knew we were expecting anyway. I went the announcement route.
I agree with the pp's who say take the high road to a certain extent. Sounds like you have been doing that for a while! I think a congrats will be fine, with a request to be sent an announcement when the baby arrives. Then you can decide to send a gift or not.
At least it makes a good story, right
