So you got dumped.
Welcome to the party, pal. Suck it up and listen to me, or waste a few years suffering because you ignored me.
The choice is yours. The mugs, the jewelry, the clothes, the toys, the whatever.
Any art made for you, any knickknacks, any movies or games. Anything that reminds you of them needs to go into a box or bag immediately, if not straight into the trash.
So listen to me on this one. The point is to remove them from your life, not continue to carry that shit around with you. I balled the entire time I did this, but I did it.
Open up that contact name, block that number, then delete that shit. Go to your text messages. You need to focus on the fact that this person said they no longer wanted to date you.
