You being "scared" indicates to me that you're not completely comfortable with the situation after all. There's absolutely nothing to risk in mentioning this to anyone. There's nothing that will punish you for putting words to it. Note that when we (feel like we) carry things around on our own, it can mess with our well-being. Better to communicate, if you ask me. But hey, you've already talked about it in here. Maybe do some more of that, and figure out what you think you're scared about. :)
