I recently asked a question about my (now ex) girlfriend who wanted to get married but I didn't. With a lot of thought I went to talk with her. We couldn't compromise on any middle grounds. So I asked her if it's best that we just break up. She left and didn't say anything. She later texted me and said "I guess so". I know my stance on this situation won't change however part of me wants to go back and tell her I will just to get her back. Any ideas on how to stop the feeling of wanting her back?
