Army less than two months.

So my boyfriend is leaving to army in less than two months. He supposed to leave in the middle of the summer but they told him either in a week or less than two months... Of course he chose those two months so we can enjoy our time and discuss everything we have to. In my previous post I said I will support him because the love is strong. My friends keep telling me it's a teenager love and to let him go so I can enjoy my life instead of sitting and suffering. Three years with one guy changes you and no matter what, you want to stay with him. He is going to miss my first day of senior year, my birthday, his birthday and the most important - our anniversary... How do you girls do that? How do you let your men go and get through this time? Yes I'm young and probably stupid, I can already see people laughing at me but when you find the perfect guy even when you are in high school, you just don't want let go of it...
