Is it my fault that I hurt my parents' marriage?

Please give me advice as I'm sick to my stomach at what I'm just did. I don't know if I should try to fix it or just stay out of it.

Some backstory: my parents marriage has been Rocky throughout the years. honestly, my mom should have left my dad a long time ago but she has no education and she has no way of supporting herself, especially when there were kids living in the house. when I was a kid I overheard my parents fighting and my mom mentioned about my dad cheating on her. Of course in the fight he denied it, and to this day I don't really know what is true.

Well fast forward to now, I got a Snapchat from somebody that I have not talked to in a long time. Kind of one of those things where we haven't spoken, but there wasn't a falling out so we're still friends on social media. Anyways, she sent me a Snapchat with no caption of her at work (She works at one of those places that has bowling and laser tag and stuff like that.) And this guy in the background looks exactly like my dad. Like, twin alert! Since you can only see a Snapchat for a couple of seconds I couldn't get that good of a look, and we haven't spoken in a really long time so the only natural reason I can think that she was sending me message directly was because she saw my dad where she worked. I get on the group text I have with my parents (to send them both baby pictures) and I make a joke about them going out and having fun without me. I included plenty of wink and smile emojis to get the point across that I was totally kidding.

That's when the s*** started.

My mom called me a few minutes later asking what I was talking about. I explained to her the message and what I saw and she completely loses her mind. Wondering when the message was taken, wondering if there's some way I can see it again so I can screenshot it and send it to her, and just getting paranoid. She specifically asked me if there's someone else in the picture with him and I say no. At the angle it's taken I can only see him. She says "Well there's a reason she sent this to you! She wanted you to see it!" I basically tell her everything I know and that I can't help her any further.

Then my dad calls a few minutes later. He's pretty calm and chill on the phone, and asked me to clarify what's going on because apparently my mom called him completely losing her mind. He said "your mom said that someone sent you a picture of me out on a date with another woman." Now, this is where I get a little pissed, because she specifically asked me if there was a woman in the picture with him and I said no. So I re-explain the whole story to my dad and he's like "Well that's weird because it wasn't me. I hate bowling" 😂

anyways, while all this phone conversation is going on I'm snapchatting my friend asking her to clarify if that's my dad and if that's why she sent me the picture. about an hour later she snapchatted me back saying that it wasn't my dad that it was someone who looked a lot like him and that's why she sent me the picture because she thought it was funny. Would have been real nice if she told me that when she originally sent the picture.

So I call my mom to explain so she can calm down and she loses her mind on me. She told me that I'm not being responsible by "trying to start s*** without getting all the information" and that "The smart thing to do would be to clarify in the first place before I try to cause drama in her marriage." She then told me that you don't have to be romantically involved with someone to try to be a homewrecker, and doesn't understand why I always need to cause drama for people. She told me that since I'm a student I obviously have too much time on my hands and I just need to go back to work.

My mom hasn't spoken to me in a couple of days. I haven't tried either though because I've been scared. I've texted my dad and I haven't gotten any response either. I feel really awful because I feel like I caused a huge fight and rift in their marriage. I honestly didn't mean to. I was just trying to joke around that I knew what they were up to that night because I thought it was my dad in the picture. I feel so awful. I never meant to accuse my dad of cheating, or plant the idea my mom's head. I don't know if I should reach out and apologize again or just leave it be. Sorry for the long post.
