<human>: Can you succinctly summarize the text in 1-3 sentences?

Sorry for the wall of text!!

Okay, so I went to the other end of the country (UK so not that far really) to look at a dress I loved over the Christmas holidays. It was a last minute appointment and my mum couldn't make it, she was having a huge dinner party and would be cooking all day. I thought 'fair enough, its just a trying-on day anyway and I have other dress appointments she can come to'

Well Dress-Day comes around and I even said to my Dad (who came with me) that I would NOT be buying a dress today, this is just to try the dress on. (Should point out that the designer only has 1 shop in the UK and thats why I was going across the country to try it)
We get to the dress shop and try on the dress, I wasn't wowed by it, nevermind, but while I'm here I might aswell try on some more. Put on another blush coloured dress and I love it! My Dad loved it, my brother turned up later and he loved it. I put a veil on and I was sold. I've looked online and through magazines and never found anything I've even remotely liked but this one was just beautiful.
We then rang my mum and did a video-chat. She saw the dress, liked it and she gave a thumbs up. 

I bought it, it is mine, its been made and will be back April-May time!! So excited. Whilst I was paying the deposit and getting measured up my brother got a text from my mum saying 'wish I could have been there' and its hit me like a tonne of bricks since.

I feel so guilty. It wasn't her intention to make me feel guilty, I rang her after the appointment and said we talked and honestly she is fine with it all. But I can't get rid of the guilty feeling like I've taken a moment away from her. 

We're going back to for the fitting and to get accessories and a veil etc so I can do that with her, but what can I do to shake the guilt?
<bot>: Mum wasn't there when I bought the dress, not I feel guilty because I've taken a moment away from her. What can I do to get rid of the guilt?
