Well that's good to hear. Perhaps she is going through perimenopause, in which case seeing a Dr. would definitely be a good thing to do. Be wary on this though, while she truly could be going through this, it could also be another smoke-screen. Encourage her to follow-through on seeing a Dr. about it
Also....when she said "don't touch my breast when I'm having a hot flash."...did you ask her, how will I know when that is so I can avoid doing that? See....my reaction to her comment (while she could be truly perimenopausal) was more of a put off. Now, if she truly did mean it that way, that the touch irritated her right then.....then ask her where you can touch her that is "ok"....not in a snotty way. Just in a "I'd like to touch you, so please tell me where it's ok"....so you know where you can touch her when you feel like it.
