Accept Relationship Advice From You?

Why are people so quick to tell you what they wouldn't put up with in a relationship? "Chile if I were you I wouldn't put up wit that!" SIDENOTE I'm not speaking of my good friends who honestly have my best interest at heart! I'm talkin about the ones who are single, BITTER, jealous and any other adjective you can think of. Don't get me wrong, I'm not the type that will put up with just ANYTHING. You won't cheat on me and get away with it, if you want to cheat just break up with me! I've been cheated on before, and my ex went out of his way to show me that he was sorry and he regretted it. And you know what? I believed him. But the thought of another girl would never leave my mind...I would always think WHY?! What could I have done to keep you with me? What was I missing that she provided for you? And aren't I still missing it? What's different now? It would've never been a healthy relationship because I lacked trust in him, I lacked confidence that he would stay with me. You also won't put your hands on me and you won't come between me and my family or close friends. That's the bottom line. So why do you feel the need to say to me that you wouldn't put up with him going to parties without you? You'll never have a man, if you don't trust him enough to be able to do the right thing when he's alone..Why are you with him?
