This sounds like something that some might consider a boundary crossing. I think sometimes it's hard to know what boundaries should be, and it may make things risker, but it doesnt' mean it's not a good idea. It's a matter of balancing, and sometimes crossing a boundary is a humane act from another person. My experience is that the important thing is to talk about any weirdness that happens from what I assume is a very generous offer. I wish you well.
