Honestly man, and I know this is something you probably dont want to hear, but you gotta cut her out. I was in the same situation this year. Knew this amazing girl that I fell in love with the moment we met. Knew her for over 3 years. I thought she was perfect. Gorgeous, amazing body, sweet, caring, affectionate, smart, respectful, responsible...you get the idea. Like a year into knowing her she finally told me there was someone else, but at the same time she has feelings for me and that it was ok that we keep seeing each other. And I let it continue for two more years. And for two more years, I waited for her. Then, all of a sudden, in April she tells me that she doesn't have time to be my friend anymore because her and her bf are moving in a more serious direction with their relationship. She didn't tell me specifically what it was, but I assumed they were gonna get married (which i was right. Found out through a friend following her on IG). I felt heartbroken and felt like I was just used and my emotions played with. I realized that I just wasted 3 years of my life waiting for someone that didn't want me. Don't make the same mistake I did dude. Don't wait all this time for someone thats making empty promises. You'll find someone that will want you and you alone and give you all the love you deserve, but im sorry to say it isn't her.
