Hello, me and my ex broke up in march and we lived together for almost a year. One day I didn't think things through had second thoughts and left. Now we are like best friends again. She's always there for me when I need something and I am for her. I help her out with her girls whenever is needed. We talk to each other or text everyday flirt and so on. I know I made a mistake and I want her back I don't think there's anyone else I know her and her kids' dad are close but she has told me they're not together. What should I do I'm so confused?
