Nobody said breaking up with someone you love is a walk in the park. Trust me, I know exactly what it's like. It's been about a year since I've been broken up with my ex. We went out for a little over a year and a half, I did love her. A lot. I still have feelings left over even still.
Trust me though, if you can deal with this, you can deal with anything. And once it's all over you come out with so much more knowledge and insight. You'll feel like a completely new person afterwards.
I'm not gonna lie though. If you're truly in love, it will be the hardest thing you've ever had to face.
