My wife and I have been together for 12 years married 10. We went through some tough times a couple years back. We didnt think we loved each other anymore. We tried counseling, therapists, I even let a shrink try some medications that altered my chemistry to see if it helped. What finally did it for us was we started to just talk. With our busy lives that was something we didnt do much. My advise for all that its worth (not a lot) is sit down with her and talk. no yelling no accusssing just sit and ask how she is what is she thinking what is wrong. And you have to ask your self thesame questions as well. Dont get defensive and dont say nothing is wrong if she asks you. JMHO take it for what you will. And good luck.
