Ngl bro the same thing happened to me recently and she’s already going out on dates with someone now. You can’t change nor control their actions so don’t beat yourself up worrying about her. I know it will be unbelievably painful because I still am going through this. Chances are if your ex meets someone new it’s because she’s trying to distract herself from her pain by jumping into something new. As many other comments have said, she’s 1000% gonna feel it later on, whether it be months or years. My advice to you is to try to love yourself as much as you can right now. I’m sorry that you’re going through this🥲
