How to handle this....

Brittany • 19. keeping track while I make bad decisions
He broke up with me after 2 years....We have both been having problems in the relationship but other than that we're amazing, he is amazing. He hasn't answered any of my phone calls or text.... I live right down the street and i just want to walk over there and talk but I'm scared.....They probably think I'm crazy but i love him....I know i shouldn't use our relationship as a threat and im not going to anymore....I focus on us more but he needs to also.....I talked to his Mom she said you guys feel the same way...That we're not good enough and that we don't make each other happy.... Should i keep going to get him back?
