Save-The-Date but no invite?

Do you want to go? She sent a save the date, which is effectively a pre-invitation. I'd let her know you haven't received your invite and provide the new address. If you're uninvited, she'll have to do some explaining. She's the one that made the etiquette mistake, though, so I wouldn't worry about making her feel bad. She can deal with the repercussions.

This might just be me...but I would say something like "I have moved since I received your Save the Date for your wedding. My new address is [address], just in case you need it."

Personally, as the bride, I was more annoyed when a guest didn't tell me that they moved and I received the invitation back....then had to resend it out

Hmmmm that is awkward. It's possible it either got lost or mixed up somehow with your move. I would contact her and say something along the lines of what @Future_Flaherty suggested. Hopefully she doesn't have any explaining to do.

Just call her, if you don't talk often enough to pick up the phone then I really wouldn't sweat it to begin with. Might be as simple as she hasn't sent them or it got lost in the mail. Also if you don't talk that much she might not be inviting you anymore which in any case I think would be something she can tell you without it being rude on your part.

My co-worker was having health issues prior to her wedding and she didnt send out invites until 1 month prior to the wedding and had an rsvp date of 7 days later. So maybe she hasnt sent them out yet....?

I think it's fair to reach out if you received a save-the-date. It's not like you're just assuming you are invited - the bride told you as much with the STD!

Up to 10% of invitations get lost in the mail. If you got an STD, you have every right to ask without feeling pushy. Just call her.

If the roles were reversed, wouldn't you want to know if someone didn't get the invite? And 4 weeks is cutting it VERY close if she's not mailed them out yet, considering 6-10 is normal.

Since you received the STD, I don't think there is anything wrong with reaching out and giving your new address. If you don't though, she will probably be reaching out in the next week or so anyway because she will be doing followups on the RSVPS that she hasn't received.

I'd say give her a call since you got the STD. It's possible it got lost in the mail.

Mail forwarding delays the mail by quite a bit, and causes it to get lost sometimes. Just ask her if she sent it. Your RSVP will be due very soon, you def don't want her to think you haven't rsvp'd! Let us know what she says.

I hate calling so I would text... Hey girl! How is wedding planning coming along? Just checking in because I hadn't received your invite and just wanted to double check.

Honestly if you are afraid of awkward I think a phone call is a way less blunt way of doing it... but i think at this point its all about personal preference

It may have gotten lost in the mail. Flat out ask her, maybe it hasn't gotten back to her. My mom mailed my bridal shower invites and a month later one got returned, bc FH's cousin moved and didn't tell us. This happened to me 3 years ago. I got a STD from this girl I knew who lived next door to me for a long time than moved. I got the STD and the bridal shower invite. Than my mom gets an invite and I don't. Weird right bc I was invited to the shower and got a STD. Her mom emails my mom and says "the RSVP is next week and you haven't responded." So my mom emails and says "I'm mailing it today. Question Heather never received her invite." And the mom answers "well me and husband are helping pay for the wedding and husbands job is on strike and I lost my job, so we had to cut back on invites." I couldn't believe it.
