help I need advice

Sabrina
Someone please help. Me and my husband had a great relationship. Sex was good and frequent. Now we have hit a rough part. He only wants to do activities that he is interested with most of the time. I try to be spicy and he doesn't acknowledge it. He spends more time on his phone than talking with me when we are home together. And for the past two weeks every time I try to get things going I get shut down and he makes up excuses. I tried distancing myself to see if that would do anything but he just continued to ignore. I feel like we are failing and I don't know why. I think in my head now I understand why people start to seek others when their partners turn off completely. What do I do.
