I think as long as you don't keep anything from each other it's fine. You'll probably laugh at me of all people talking about honesty, but you're the one who made this commitment, not me. Best thing to do is not blow it by pushing him away.
Consider compromises, too. If there are certain people he doesn't like, or you don't like, maybe talk about it. I've had to think of things since my sister got here. Things like, "what would I do if the boy she liked showed up?" I'd probably run. Every time I saw him, every time his voice reached my ears, I would run. Even if it meant consequences or falling in bed with someone more embarrassing.
And if he and I ever fight to the point he doesn't want me around you, then I can do that for you too. If you'd both want that.
3/3
