We all know Ariana Grande is grateful for her exes...But do we all have to be? Sometimes when a relationship ends, it's easy to let the pain blur your vision and assume it was just all a waste of time where all you took away was a dirty hoodie. More often than not though, Queen Ariana is right and there's a lot to learn from every past relationship, even the ones that send you into a six month wine-crying, ice-cream binge. Being vulnerable with someone else, even if it doesn't work out, is always worth the risk. Or, at least that's what movies tell us...When a Reddit user asked the internet, "What is a lesson that your ex taught you?" the answers ranged from deeply profound, to inspiring, to cringe-worthy and very matter-of-fact. Some people learned new languages, cooking techniques, or the power of respecting yourself and your choices. Time might not heal everything, but all the pain our exes cause only makes us better for the people we're supposed to be with. Right? Did I get that from a mug? Regardless, we're so f*cking grateful for our exes.1. Straight and to the point, "RonSwansonsOldMan." If you marry the wrong person, you WILL pay for it, emotionally, psychological, and oh yes...financially. 2. This is real, "refreshing_username." There are things you can't un-say. 3. Hard truths from "xmittsx87." Don't take people for granted. Don't assume that they know how you feel about them. Tell them, show them. 4. Great tips from "pupsnpogonas." Alright these are pretty depressing. So something GOOD I learned from a shitty ex was squeegeeing yourself off before you dry off with a towel after you shower. Like I just run my hands down my arms and legs and flick water off before I grab my towel, and it seriously keeps the towel from getting absolutely soaked. But yeah, that was the only good thing I got from that relationship. 5. This is deep considering it came from a user named, "suchafart." Just because you don’t fight doesn’t mean the relationship is good 6. Wow this is pretty insane, "nuts69." Don't leave your laptop unlocked with social media logged in, because she will methodically message all female friends trying to 'seduce' them in order to see if I'm cheating on her Yeah, she fucking sent sexual messages to like 20 of my old female friends from high school that I never talked to in 10 years. Had a lot of "WTF YOU CREEP" messages. 7. This sounds like it came from Oprah, "TealHousewife." If someone tells you that they're a bad person that will only end up hurting you, believe them. 8. Shoutout to Bojack, "ThePotatoesWereFine." I learned a lesson after a Bojack Horseman episode, and it was, "when you're wearing rose-colored glasses, all the red flags just look like flags." It made me rethink a past relationship and how clouded my judgment was simply because by being in love. 9. A powerful equation from "HerezahTip." Actions > Words 10. Wise words, "FakeInternetPointss." Don't loan them any money. I'm still trying to get money out of my ex after 2 years of her promising to pay back a large purchase I'd made while we were together. It's like pulling teeth. Keep your finances YOURS. 11. Well this is definitely true, "Babyseals84." They never cheat just once. 12. Sounds like there's a story here, "BasedZiggy." If your friends say she's cheating on you, she's cheating on you 13. Valuable skincare lesson from "mrwinky531." The earlier you start moisturizing, the better. 14. Damn, "TheStiffmesiterr."

This is definitely helpful, "toan55." introductory Mandarin 101. 17. Did movies teach you this already, "pllove?" That I shouldn't trust someone just because they have a pretty face. 18. Very wise, "Not_Very_Tasty." Taking care of a selfish person doesn't make them appreciate you. It makes them more selfish. 19. And a valuable cooking tip from "malenablah." I've learned that after chopping garlic you can rub your fingers against metal (the sink for example, stainless steel) and your fingers won't be smelly anymore. 20. Honesty is important, "JiveTurkey1000." "I play a lot of video games" "Teehee ok!" "No, I mean it. I'm not lying to you." 6 months later "Omg stop playing video games!!!" It's rough out there, but at least we walk away with some lessons!
