My girlfriend broke up with me because she found out that I sometimes Spotify-stalk people on Discord.
Why are you stalking others online?
I like to see what they are up to.
I can see where she's coming from. Seeing you do that could make her think you would go even further to actually stalk someone and that would be really messed up. Try talking to her and letting her know you would never go that far.
I know I'm good at apologizing. I'm going to show her my changed behavior.
I am glad you are concerned with your behavior and this is a good initiative to show. Your relationship will be stronger because of your understanding.
