I don't listen to Taylor swift but this song fits...I get back with my ex after 5 years apart cause one of reasons we split was my drug addiction but I cleaned up got her back one week before our 3 months I got feeling something was wrong I didn't say anything cause I didn't know if it was true but turned out she was cheating on a guy in our group I was devastated cause she just ended an abusive relationship the same month we got together and she led me to believe she just "need a few days were still together I'm coming back" n then I got the text from the guy like it was perfectly okay
