I'm with Penguin (wait...Penguin? That's not the name I associate with that photo. You kids and your crazy name changing...). Your boyfriend is probably reading doubts about him into your phrasing. I was going to say guys are sensitive about these things, but come to think of it, women are too. People in a relationship listen hard for cues about how you're feeling and how committed you are, so make sure you aren't communicating indifference to him if that's not what you mean. Your family, though -- tell them whatever you think is best.
Me, personally, I've been saying this is permanent, because I'm older and it probably is. On the other hand, I'm not sure that's how I *feel* about it. I moved away from my home state 30 years ago and I still can't accept that I'll probably never live there again. It's like I have this instinct to drag my bones back there to die or something.
