definately go, its a fantastic opportunity, italy is a wonderful country, it will benefit your degree and future job prospects, and you wouldnt see your boyfriend for that whole time anyway! If its meant to be sure you'll miss each other, but you'll be even closer when you get back. it would be awful to not go and always regret it. It is a big step going by yourself, but once you've done it, you will probably feel proud. Also if you really hate it, i.e the family arent nice, just come back, you dont have to feel bad for leaving them if they arent nice to you.
