Guy Situation

I wake up every morning, grab my phone, and text you good morning. I don't actually send it to you anymore. You hate me. and never wanna see or talk to me again. but I love you and I know you love me. I messed up and so did you. but you don't need to treat me like I don't mean anything to you when I know I do. you mean so much to me. There really wasn't anything wrong with us until you started falling for a lil girl. I mean... your 18 and I'm only 22 days away from turning 16 and she just turned 15, like three months ago.. that shit is wrong. I'm not saying us being together would be right but it is better than that. and she is such a lil girl. isn't is when you go from one girl to the next you are suppose to upgrade and go to someone better and prettier and all that?? well I thought I was pretty and beautiful and all that good stuff but by doing this for like the third time... your making me feel like I'm just some normal girl that isn't pretty or that means anything.. Really?? That's not right. I'm not trying to be conceded or anything, but I think I have the right to be like this at this point.. I mean is this a bad situation? or am I just overreacting bcuz I love this guy?? Anyone have any advice? Comments? Anything?
