i honestly don’t know what else to call it besides a relapse. we haven’t talked in over half a year, we aren’t in each others lives, we both have moved on from each other, but some days i feel this need to see how they’re doing or what they’re doing. when i give in i’ll check his social media briefly &amp; just feel like shit doing it. this person treated me terribly but mostly unintentionally as they had their issues as well, so i don’t understand why i feel this overwhelming need to check on them or even potentially reach out to them. it’s made worse by the fact they still keep some of the pretty things i said to them on their profiles. 
has anyone else experienced this? is it normal?
