Should I be this bothered??

Sorry this is so long, but I though you should know some backstory.

We had a good 10-12 guests who didnt show up, who didn't call to say they weren't gonna show up, who didn't apologize after the fact, and didn't send any money to cover the loss at my wedding.

Out of all the no show's to my wedding..the one that hurts the most is my ex-best friend. We were very close throughout HS and afterwards, she was my partner in crime. But things started getting funny towards the end of our friendship. She started going through some personal things, and ended up getting pregnant. Around that time I met DH and things were going pretty good between us.

She didn't like him or his friends and told me 'If you ever marry him I WILL NOT COME, so don't even bother to invite me '

She fell off the map for a good 2 years, and then reached out to me to rekindle our friendship. I always knew our friendship could never be the same.. and with the separation between us I realized she was a jealous person and that is why she behaved so nasty to me right before she fell off the map, but I decided not to cut her out of my life completely.

We spoke occasionally on the phone and I would update her on my relationship progress...but we never had the friendship we once had and only hung out a total of 2 or 3 time over the course of 2 years.

When DH and I got engaged, I reminded her of the hurtful thing she said 2 years earlier..she claimed she never remembered saying that.

I start the planning process, and we continue to speak by phone and text. One day she said that at this point in the planning process she has to assume that she is not in the bridal party since I hadn't asked her. And I had to tell her that she would not be in my BP. I could tell she was hurt by that, but I didn't want to have anyone in my BP that wasn't gonna be truly happy for me, and I didnt want to deal with no one's drama.

Anyway, she begs me to invite her mother and sister who I wasn't planning on inviting and I agreed.

Fast forward to the wedding, we didnt have a receiving line becuase of time restraints, so we tried to visit each table at the reception. When I finally make it around to where she should have been sitting..who do I see? Her mother and her sister..but she is not there. So I asked her sister, and she looked so emarassed and told me she didnt come. Why? Becuase, get this..she had her period..***?

I was really really hurt by this. So hurt, that on our way the airport the next day I was thinking about. it.and found myself thinking about it in Mexico..but I put a stop to it because I didnt want thoughts of her to pre-occupy my mind on my honeymoon.

Now that I am back, I still havent heard from her and am debating whether I should text her to tell her she hurt my feelings...talk to her, or just write her off completely.

It's been nagging me. What should I do?
