How to check the activity of another person's phone?

How to check the activity of another person's phone? I think my husband is cheating on me and I want to check if he is communicating with someone or not. Please advise me some way

Hi, I think my advice will help you. I had this problem once too, I was sure my husband was cheating on me but I couldn't prove it. I met with a friend, told her my fears and she advised a website https://topspyingapps.com/free-text-message-spy-without-installing-on-target-phone/ through which I can find out the whole truth. When I got home I did everything I needed to do and found out that he was having a very active correspondence with our neighbor Lily.
And when he was late at work one more time I decided to visit the neighbor, and I was not surprised to see my husband there.

Good
