I write about once a week with my ex. We broke up over 3 years ago and didn't talk at first, but later we both confessed and cried together and really helped each other understand why it didn't work out. We don't talk on the phone, I think that would be too much to handle, and we both agree that we shouldn't get back together. But we know each other better than anyone else, and we use each other to vent and talk about our current troubles with work and dating. Sure we aren't really a thing anymore, but it doesn't mean we don't still love each other, and we both look forward to reading each other's emails.
