Broken hearted- juicy story btw

Okay so my ex was with this new girl and I honestly didn’t rlly care cuz it’s been six months since we broke up. But my friend one day texted me and said omg i was with your ex and he said you’re hot ( I totally trust her, it wasn’t like that) and the new girl and him broke up. And she said add him back on snap cuz they were talking about it and I was like ok yeha and I did. He immediately snapped me and said sup. Okay so we were talking so much and ALL THE feelings came back. I felt exactly like I did before. I was so happy and we were talking for like a week and we were gonna hang out but then he started acting weird and I was like wtf. Then my other friend told me that he started talking to his ex again and I got so mad and I legy him on read and was acting rude. And I tried to get the truth out of him but it didn’t work. But anyway she texted the next day and asked if I liked him and I Said we started talking like a week ago but I didn’t know you guys were talking so I’m fr sorry. And she’s A BITCH and was rude asf to me when I apologized. And she asked what we talked about. Anyway he texted me and said he has feelings for her. And i said Ik. And he asked if she texted me and i said yeah and I kinda went off on him and said how tf was I supposed to know you guys were talking and he said we weren’t. And then he said can u do me a favor and I said what. And he said can u tell her that we only had small talk and barely even talked and I said that I like her and told you that I like her and not me. And I broke down just balling. Like he didn’t care about me and my feelings. And nothing about any of that was my fault and she was being a bitch to me. And I didn’t do him the favor and I blocked them both. It’s been a few days and I’ve been crying myself to sleep. I’m so sad idek
