My life and what I'm about :]

Have you ever had a problem, that you needed to tell someone something that they needed to know, but you didn’t know how to because you’re afraid that once you tell them it will get turned back around on you and they’ll believe someone else over you???? Yeah, that’s what I’m going through right now. I NEED to tell my boyfriend something that’s bothering me so much, but I fear he’s going to talk to the other person about it and it will all be turned around on me!!!! Ughhhh HELP ME!!!!!!
