How do I get over my ex?

Obviously Krista wasn't that great. You are a beautiful special human being and you deserve someone that understands that. It does suck when a person you love decides the easy way out instead of sticking it out with you but when that time comes look to those that have real love for you. Hang out with your best friends and watch movies, have them spend the night and play videogames and eat junk food and bash on girls. Realize that they care about you way more than Krista ever could because they are there for you. Spend time with your family making smores and playing scrabble, if you live where there's snow make a snowman. You have to realize that Krista has no power over you. Think of you two splitting up as an upgrade. You are now CLOSER to the lady of your dreams. You are now free, you can find HER. You can act crazy and have time for friends again! Go have a great time, forget about the ones that don't matter.
