So my ex girl and I have been broken up for almost 4 years. Been 1 year since we last talked. We were long distance. I don’t want her back and never get sad or depressed over her. However I still find myself thinking about her a little each day and dream about her at least once a week. Why does this happen? I do have concern about how she is doing because last time we talked she wasn’t doing great. Thought about trying to reach out and be a friend since I have no desire as of now to get back together. So why do I still think of her? And is it a bad idea to reach out as a friend?
