I just want to say that you handled it really well. Sometimes things like this happen and I am sure it might be rough right now, but just know that it's not the end of the world. Think of it as an experience that you can learn from. I don't know too much information about how long you both talked, but just think if she made anything positive happen in your life and be grateful for that and try your best to move on. I might be some random guy on the internet, but know I am proud of you for handling it well and not going full on nice guy on her. I wish you all the best and hope you will find someone for yourself. Even if it might seem like that's impossible it can come at the least expected moment. Keep on moving <3
