Needing advice

So my wife and I have been together for just about 8 years. We are now going through a rough patch where she feels like we have slid into this just friends stage and she is not sure that she can get the romantic feeling back. I know this happens a lot in lgbt relationships. I think a lot of it has to do with her level or work stress and the amount of time she spends at work. I don’t feel the same way she does and it’s heartbreaking to think I could be losing both my best friend and the love of my life. Do any of you have any advice or have experience something similar and been able to get through it?
