Mad and lost. Downright confused

How can someone do wrong by you, confess, and the promise to do better BUT only get worse. I've moved on from the situation but to continue to display the same actions is downright bullshit. The words don't line up with what your doing. I'm so pissed because you want me to sit here and look crazy while your out in the streets. Empty promise and lame excuses. My is favorite is "I'm trying to get my head together". I say I've given you plenty of time but what I won't do is live like this. I need peace, I need honesty, I need a commitment. People don't have 3 and 4 years just to waste on a person and that's why when the problems started happening I wanted them fix BUT now I just want to give up and walk away. HeLp!!!
