How to Find the Courage to Leave a Relationship You've Outgrown

I'm so bad at cutting off relationships because i am just, lke, so scared of hurting the other person. I think my biggest fear though, was the fear like starting over. When you're so comfortable in a relationship, it's hard to walk away from that. Once that thought comes in, it doesn't go away. You have nothing else in the future if you're just like working off of this like, shaky foundation moving forward. If someone asked me, wou nont why joyes break up, there's really no like, reason, other than the fact that i just needed to grow up and learn to be all my own.
