Heartbroken and Alone: My Ex Cheated on Me

this is more of a vent!! I miss my ex so much. I know I already posted about this, but I don't really have anyone to rant or vent to about it. last Monday I found out my (now ex) boyfriend was cheating on me with his ex, and I'm so heartbroken. I'm glad I found our now (1 ½ months) rather than 6 or 7 months down the line, but it still hurts so bad. he was one of the only guys I truly trusted with every part of me. I'm trying not to think about it, but it's so hard. I'm just really depressed about it, it's making everything worse. I told him I didn't want to stay friends, and I know it's for the best but i wish i could hear him say something really dumb and we both die of laughter. I miss him so much. I got so attached to him, and then he cheats on me. I thought he could be trusted, and he betrayed that. it hurts so bad.
