He broke up with me

He left me because he realized that I was just a filler.You know how they say to get over a girl you get with another one. I was the other one. 8 months into the relationship he realizes he was not happy, And then he kept at it with me till he couldn't anymore. We hit our 1 year and one month and a few days..and he ended it. And I am so upset because they went out for 3 months and the chick didn't do anything for him or try to talk to him or try to go out with him or anything. A chick that didn't have a care in the world about him, ruined him, which in turn ruined our relationship.
