she left me cuz of my poor communication skills

We were really good friends but I always had a crush on her. I loved her for 2 years, and she said she started to develop some feelings for me. We started dating and we were a really good couple our relationship only lasted 1 month, because im a shy and insecure boy. I couldnt find things to talk about, and I couldnt approach her because I think I am too ugly. I didnt know my poor communication skills bothered her that much. On a random thursday she left me. I begged her to stay twice but she said it wasnt about me and that she was depressed. She said she still loved me and we flirted for 2 weeks all of a sudden, she said she didnt love me anymore after giving me so much hope. I still love her so much and we are still friends but I dont know im scared to lose her even though I already lost her
I’ve said this to someone before, most girls are just attention whores. Focus on yourself and let the right one come to you. Chasing girls young will ruin your potential.
