You guys...I need some MAJOR advice...please? I'll do anything for your help...comment stories, poems, anything.

So Me and my boyfriend will be together 3 months on the 19th and we are very very VERY happy. But I have a secret...and It's killing me keeping it from him.

My cousin had a graduation party about 2 months ago (a day before our 1 month) and this guy got me alone and kissed me. I shoved him off and told him I had a boyfriend but he kept trying to get with me. So I was walking away and he kept smacking my butt and I kept yelling at him to stop and I hit him a few times too... and then I managed to get away.

I told my boyfriend he was trying to kiss me but didn't because I was scared he would leave me...I couldn't take losing him, he was the best guy I have found. Hes so nice and a really good guy and I feel horrible about hurting him so I feel like I need to tell him the whole truth...

My best friend says not too but I think I need to....What do you guys think?
