My brother and his gf broke up, now he’s with one of my exes

My brother (24M) and his gf (22F) were together for about a year. Their relationship was very loving and gentle, it was really sweet to see. His ex recently went out of country for a couple months due to school. At first my brother was really cool about it but soon began to miss her. They would talk on the phone everyday but he was still feeling lonely.<br><br>I’m (22M) the virgin here so you can see where this is going. So, my brother fell into a depression last week and went out to a bar where he saw my ex (22F) and got really drunk with her. We all went to high school together. They were both just talking and having a good time but things took a turn for the worse and they hooked up. He didn’t tell me about it but my ex did. I was in shock. I’ve been avoiding him since but he just came up to me and told me that he’s dating her and he’s sorry. I’m crying as I type this out.<br><br>I’m just angry at the world at this point. Why would he do this to me? He’s my brother for crying out loud. I’ve always gotten the short end of the stick and it seems like I always will. Life just keeps kicking me in the nuts and every time I fall, the ground gets harder.
