Shower Obnoxiousness

So it's not secret that I'm getting married.

One of my best friends asked to throw me a shower when we got engaged. He was all excited about how he was gonna do it and where he was gonna do it and all sorts of fabulousness. We set a date (Aug 31) and he was going to have his boyfriend send out invites. He started to ask me for addresses in July. I gave them to him at the beginning of August, figuring everything would be fine.

However.

He has since broken up with this boyfriend. He told me that the invites would still be sent out. I started to bug at him for him to send out invites right after I sent him the addresses. He said they'd be done one week, then the next. I called and texted to figure out what was going on. It wasn't until I send a slightly nasty email that he responded, telling me (on Monday of this week) that people should have started to receive them since he sent them "a couple of days ago."

Now.

It is Thursday. I have spoken with different people from all over, trying to assess if they've received invitations. No one I have spoken with has. He texted me yesterday asking if we could get together to discuss stuff and I texted back yes. He never responded so I called him. He yelled at me that he was at work and couldn't text back (how he could answer the phone and not send a text is beyond me). He told me he got off at 7:30 and that he'd call me then.

7:30 came and went.

I phoned him at 8 and then at 8:30 I set him a text. No response. Nothing. Nada. Zip. Zero.

My sister (MOH) knows how upset I am over this. I want this shower to happen (it's the one with all my girlfriends) and I want it to happen on that date. She has decided to take over the resonsibilities and has asked me to send her all the phone numbers so she can call people and explain that it's been changed and will be at my parents house.

I have decided to wait to see if it comes in the mail today before I send her the phone numbers. I want to try to get a hold of him, but it seems as though he is ignoring me. I plan to send him an email since it's the only way I was able to get him to respond last time. I don't want to be mean, but I'm so frustrated that I'm ready to cry!

My sister is demanding the phone numbers and says that I owe my friend nothing because he did nothing. I feel like I should give him one more day, but my sister again says I owe him nothing because he screwed me.

Thoughts?
