AIBU to not go to wedding after frozen out of hen do?!

[dizzyfairy]

First time posting...

Friend A is getting married, I'm completely over the moon for her! We are work friends who clicked straight away and I really value her friendship, however I don't think it is reciprocated anymore :(
She moved here for work- away from hometown- and lived here for a few years during which time she met and became engaged. Last year she handed in her notice and moved back home to buy a house settle down etc. I miss her. A lot. Really really a lot.
Since she left, our organisation was hit by massive govt cuts with budget cut in half and I was made redundant. It was a total farce- I would be within my rights to sue- but being a charity, such would see it collapse, everyone would lose jobs and our vulnerable clients would suffer immensely. Person B -who used to be a close friend- turned out to be a snake and sold me and my job out to save herself- no one in our department would have had to have lost their jobs, but friend B decided she all of a sudden wanted my hours as well as hers (both were part time) and cut me out of her life and turned on me.
It was a terrible terrible time. Friend B and another close colleague (friend C) deleted me from social media, ignored my texts when prior to this we would text all the time, left Whatsapp groups so that I was the only one left in the group- I felt totally ostrisized and abandoned. I arranged leaving drinks for myself- not one of them came, no leaving card, nothing. They cut me out totally as they knew redundancy procedures hadn't been followed and if I challenged the process they knew their jobs would have been on the line.

Meanwhile friend A set a date for her wedding and invited me and friend B.
Friend A had never gotten on with friend C, so wasn't invited.

I called and text etc friend A as usual until I realised she hadn't initiated contact with me for over 6 months, it was always me calling her.
I got a bit depressed over the whole redundancy and while friend A said kind things and stated that she saw what they were doing and it was grossly wrong, she still gushed over their social media posts and had friend B to stay for a mini holiday.

-I would never expect A to end her friendship with B in some kind of show of loyalty, I'm not that childish-

Anyway 2 wks ago friend A text to say hi and said I had been very quiet and was I still going to wedding/hen do as she realised it would be difficult with friend B present.
I said I was nervous about it but wouldn't miss her celebrations for the world.
Initially (in March) she said I could stay at hers for the hen do, then retracted it unless I bought an air mattress to sleep on the floor due to volume of others staying- or she said I might be better booking a hotel- I did this and made sure I booked a triple room (same price) in case others needed it.
I've bought a dress, arranged childcare (not easy- lone parent, dad has no contact), done the same incl another hotel booking for the wedding, bought a gift etc etc

Today I discovered she hadn't booked me a place on the hen do.
I'm so so so upset.
Plus friend B is now suddenly invited to wedding and hen.
She said money had to be paid last week- the hen do group said money had to be paid at the start of this month, I told her I needed to wait till payday and as I'm a teacher (and have tonsillitis) it's been so hectic starting back that I only just remembered so I text her in a panic.
She said the activity was already booked and wouldn't answer when I asked if she could ask if they squeezed me in- activity could involve one participant or 100 participants-really doesn't matter.
Eventually she sent me the contact details to call and ask myself but only after I practically begged.

She doesn't want me there does she?
I'm not the type of person to cause a scene, to ruin her wedding day, but I think she thinks it would be easier if I didn't come.
Should I admit defeat and not go to either hen do or wedding?

Honest opinions please.

Oh sweetheart - this is so horrible. It sounds as if something went on when friend b went for weekend. I think you're right. She doesn't want you there does she and I think you know that? Can you think of anything you may have done to upset anyone? If not, I'd leave them alone x

Oh this doesnt look good.

I think her misplaced loyalties lie with b. More fool her tbh.
