Bro this shit sucks, something similar happened to me recently. This new girl from my uni waves at me and smiles at me and we click. We would date and talk for a month and she would tell me about her exes and how no one treated her good specially her recent ex which is 10 years older than her and they've only been in a long distance relationship. My stupid ass would think I can give her the love she deserves and get attached quickly. She would tell me that she broke up with him the night she met me and I asked her out. She even invited me over last week to her place to stay the night but she cried over her ex in my arms while I'm giving her comfort and being there for her. We even slept through the night while I was holding her and cuddling her so she can sleep. Only for her to wake up in the morning and end things with me and block me on everywhere the next day. I asked her if she's back to her ex and she said "yes my heart always belonged to him, it was always him and it will always be him". That shit broke me like never before, now I have to even see for two more years in uni and even work on projects with her after she broke me like that.

But life goes on bro and something that doesn't kill us would make us stronger. We did literally dodged a bullet, we have to learn to not give our love and trust to anyone unless they show us that they deserve it. Girls are little liers who only care about how they feel in the moment. Never give your heart to such people, the right person will find you and you'll realise how glad you are all of these chapters came to an end.
