Adult friendships and forms of Bullying

Hello and thank you for reading!

I'm in a emotionally and mentally draining situation, a short back story...

We were 3 good friends for a long time..

- friend 1 flaked through out my whole wedding and made my bachelorette party about her i confronted her when she was drunk ( clearly i shouldnt have done this) and this spiraled out of control with her screaming in my face wanting to physically fight me on my bachelorette night.. she was suppose to play a huge part in my wedding party she flaked and there was some hurt feelings on my end she stepped down, I overcame my hurt feelings and moved on.

- friend 2 also in my wedding party really stepped up and has been an amazing friend, we have no issues.. except now..

Ever since the incident with friend 1 things have been weird with friend 2 now that the wedding is over and done. Friend 1 and I have not spoken since my wedding months ago.. there has been no attempts of contact from her. Friend 2 is starting to lose touch as well I've called in the past week twice and both times gone to voicemail and I've texted this week and nothing,

I Have this feeling friend 1 is talking very poorly about me and spreading lies. I say this because I've witnesses how she talks about other people behind their backs.

I don't know what exactly I'm looking for by posting this I'm just confused and honestly feeling lonely about the whole thing and I'm hoping friend 1 isn't turning people against me thinking poorly - how can I even get people to see that those are lies if this is the case?
