Girlfriend left me after 3 years

Nick
My girlfriend and I have been dating for 3 years, We met in high school. I recently graduated and have moved to for college, She is almost done with her senior year and in the mean time I was just waiting for her to finish so we can start college together. We were inseparable, There has been a lot of long distance because I've traveled a lot for work over the past year but we still managed to kee our love close. I will be honest I've made many mistakes throughout and she has given me chance after chance only because she loved me and saw better in me, No I never cheated it was just pointless arguments while we were away from each other. Simply put we were best friends. Until recently everything was perfect, It's been about a month now since I've been single but not by choice.. She is taking a lot of AP classes her senior year of high school  and is enrolled in college as well. She told me she needed a "Break" to focus on school and she wanted me to give her a whole month...Immediately when she told me that I did to her, This is your way of breaking up without actually saying it, I will be honest over the past few weeks I've "accused" her of leaving because she found another man. Deep down I've had trust issues but I never let it ruin us because I love her still to this day with all my heart. So every time she told me she had a new "Friend" I would get irritated because she's just so beautiful and perfect and I know every guy tries to get at her and I don't want anyone taking my spot, But if she really loved me she wouldn't catch feelings for someone else right? So after the constant arguing the past few weeks just because I've been so heartbroken she finally admitted there is someone else. She wasn't happy with me anymore and instead of just waiting she found a whole different person. She still try's telling me she loves me and that she wants to get back together later on in life or once she graduates in a few months, But I don't know what to do? How can she say things like that but turn around and give her attention to another guy in the meantime. I still love this girl with all my heart and can never see myself with anyone else...Is it wrong that I still want to wait for her? She's the only girl I want she's the girl of my dreams, I just know I'll never find anyone as perfect as her in my eyes.. I don't know what to do... 🤦🏼‍♂️
This was us just a little over a month ago 😪 Nothing but happiness. 🙁
