So me and my girlfriend broke up about 3 months ago because we are going to colleges very far away from each other and didn't want to tie each other down while we were in college. We called it off, but things were still very tough. We still loved each other, talked, hung out all the time, and hooked up. We slowly however started to drift apart from each other, and we began to argue more and more. We eventually decided to stop talking. We went back and forth for about a month, but eventually we stopped being in each others lives. She began dating this guy about a month ago. Yes I'm extremely jealous, but I understand that it's probably best if she wants to move on. However, every say, three weeks or so, she sends me a text and catches up with me. Every time she does this I get a sense of hope that shell fall for me again and we will get back together. However I never say anything like I love you or I miss you. We just conversate. Should I open up to her and tell her how much I still love and miss her, how much I want her back? Or what? Why is she doing this? What should I do?
