Most Helpful Guy
Don't try to bottle up your sadness. Just let it out and then after a bit when you get control of yourself is when you need to make introspection. Think about the mistakes that happened in the relationship. See where you yourself need improvement and think about the things you cared about in the guy and things you didn't like so you can understand your type better. Spend some time must doing productive hobbies. Keep yourself busy and work on self improvement. People have different opinions on this but I recommend just staying away from relationships just for a little while until you're certain what you want for yourself and what you want to do for some SO down the road.
