It's been four years and I still think everyday about my ex. Not in the sense of needing, missing, or really wanting them-- but they come to mind. Their birthday was last month, so that lead to thinking about them a lot more than normal for me, but it's at least a passing thought everyday.
I'm really not sure how normal that is to still have such a connection to someone who isn't in my life in any way. It's better this way, but I can't help but have reminders... even four years later, everyday.
