What's the best method of getting over a heartbreak?

My boyfriend of two years said he needed to focus on himself with school, his association, Army reserves, and his part time job. Which is completely understandable, but that concluded to our relationship to end yesterday.

I felt slight relief and mild pain, but the more and more time went on the more my sanity became tested. Flashbacks and self debates happened. Random crying. And the desire to send him a 5 page text message (thankfully I didn't)

My family has been great support, especially my oldest sister. I struggle with the idea of moving on or just focusing on myself for now, since my bread and butter is helping others. I have a Colardo trip planned to visit my other sister (an Eat, Pray, Love thing I hope)

But I'm currently reminding myself to love myself, stay positive and respect his wishes.

Any advice or personal experiences?

I'm in my early twenties and yes I've had a first love break up before. And others. But this one...i felt the strongest and most trusting out of them all. We said we would reevaluate where we stand at the end of the Fall, but missing those big moments changed people and I'm trying not to have big hopes (I know how that plays out)

I'm finishing my associate's degree this semester and plan on working part time as well.
