Everyone says "once a player always a player." But

Everyone says "once a player always a player." But i'm proof that people CAN change. I'll admit, i used to play people all the time.. Lyin' & cheatin' & not makin' relationships last.. But i was young. I didn't know what i wanted. Now? I'm soon 18 & i'm engaged to a wonderful girl named Shannon. When i met her, she made me wanna change. People always hold my past against me & say i'm worthless & i mean nothin' to them, say i'll never truly change whether i think i have or not, that i deserve to be treated exactly how i treated others, & "karma" will catch up too me, etc. But what they don't seem to realize is, the past is the past. It can't be changed. I moved on from it, so why can't they? Dwellin' on it is only hurtin' themselves. Everythin' happens for a reason. All those relationships from the past, just weren't meant to be. & They also don't even know what all caused me to be that way. Gettin' my heart torn apart by my ex did a number on me. That's when all the cheatin' & short relationships & the smokin' weed & cigarettes & drinkin' alcohol happened .I was afraid of commitment. I didn't wanna get too close to anyone. Because everytime i did, they torn my heart into pieces & stomped on it, picked it back up, & did it all over again. I felt like i had to leave everyone before i was left. Nobody ever took the time to help me through the rough patch & get me back on track. Everyone ran away. They don't realize what all they say too me is doin' to me. It hurts, bad. I beat myself up over it enough, they don't need to also. Shannon actually gave me the chance to prove myself. Everyone else always gave up after one little fight. So i just want to thank my fiance for not givin' up no matter how rough it got through the months we've been datin' . I'm so glad i'm not how i used to be anymore. I'm not as afraid as committment, cause i trust her. I know she loves me & isn't gonna tear me apart like everyone else did. So i'm gonna end this with sayin, thank you babygirl. <3
