How I would deal with a break up will honestly be really difficult because knowing that you have spent you’re time and love affection and stuff like that it will hurt. Honestly I would cry a lot knowing that they will move on and I’m just stuck there still madly in love with them, and especially the worst part is having to move on. Moving on trying to make someone jealous, taking revenge on whatever the other partner did will be soooo difficult. You still will want to be stuck with them and still will want to spend more seconds, minutes, hours, day, weeks, months, years with them. You love them deeply and sometimes you will want to self harm yourself or just not be yourself no more, you just sit there and wonder how and why was the reason they left you… you deeply love them and miss them.
