Getting over a first break up

I'm 26 and the first boyfriend I ever had and I just broke up. We were together for two years and I just wanted to get some advice on how to I guess move on from this.

He was my first relationship, so I have never experienced this before. Some of the reasons he had for not wanting to be with me were not so nice, so that's kind of making me realize I deserve better than that, but at the same time he was the last two years of my life.

What are some ways to cope with random things reminding me of him and what are some good ways to help myself move on?
