Thank you. I know that he is, because I trust him when he tells me so. My friend's point was not really that H isn't happy with me (I mean, my friend can't possibly know that!), but that he would perhaps be much happier with somebody else. And he only says that kind of thing to try to prove to me that I could choose to leave if I wanted. Unfortunately, it's really not helpful for me to hear that, and it certainly doesn't mean that I do have that choice.
