would it be okay, if I moved away?

I want to move away and I have so many opportunities to, but I know that leaving here would be so hard. It seems like I have everyone here I need and I don`t want to leave that behind. If I leave, when would I come back? There is just so much to think about, it is a huge decision. The main thing that is stopping me is my boy. Why would I want to leave him? He means so much to me and we would both be heart broken. I just don't know.
