My friend ruined my surpise engagement party

Hello glow community, I really need advice. I’ve been crying all night. One of my close friends ruined my surprise engagement party.

This is the situation:

A good friend of mine, let’s call her Hannah. Wanted to throw a surprise engagement party for me this July since no one else made moves to do so.

I got engaged January of this year! When spring arrived I thought of having one in May but due to my fiancé’s grandma getting hurt, we decided to cancel our plans to make one. One of my close friends, let’s call her Marla. Wanted to help me plan one but then I told her I couldn’t make one happen for May cause of his grandma she said she understood.

Fast forward to today:

Marla was in my city visiting which I saw from her Instagram stories (I live 2hrs away from my hometown where she lives and my parents.) I asked her if she was free to connect! When I met up with her at the cafe I sat down so excited! Shes never in my city. The moment I sat down she looked over at me upset and said “Have fun at your surprise engagement party Sunday.” I looked at her confused and asked her what she meant. She said “it seems someone planned a surprise party without involving me in their plans.” My heart felt happy about a surprise party but it also sank in that moment. Why did she tell me about it if it’s a surprise? Why did she want to ruin it?

Marla turned away from me at the table and became closed off. She then said “why didn’t I hear about this until now? It’s a week ish away. Was I purposely not invited? Why do I not feel included?” And I replied with “Well you got an invite so?” I didn’t know what to say cause I didn’t plan the party.

After I saw her and went home feeling sad. She texted me a long text saying she’s angry my friend Hannah planned it. Because she feels Hannah doesn’t like her and had intentions of being mean to her because Hannah didn’t involve her about the party. Side note: Hannah and I had a short break a few years ago but worked it out and became close again after mending our friendship. Marla on the other hand hates Hannah and didn’t like I mended it. Marla is the type of never forgives or make amends with someone. She rather plot revenge. she wants me to always exile everyone.

So Marla ruined my surprise party for me and believes my friend Hannah purposely sabotaged her plans to plan me one. But my friend Hannah just really wanted to plan one for me cause no one else was doing so. So she contacted my maid of honour and planned it with her. Marla really believes my friend Hannah is against her cause Hannah blocked her on Instagram years ago when she felt uncomfortable by Marla viewing her profile constantly. I’m just lost for words here. I’m hurt she told me about the surprise. I need advice. Also I asked Hannah why she has Marla blocked and she said “oh she blocked me years ago and I saw she unblocked me so I blocked her back haha I don’t care about Instagram, I can unblock. It’s not that big of a deal. Also I don’t have any issue with her, I just find her mean to you.”

Also I never told Marla she was a maid of honour. Hannah also thinks Marla is making a big deal about the party mostly because she’s planning it. Also no one stepped in to actually make one happen and now that one is happening Marla is upset.

FYI ages of us are 27-30.
