What Are The 1st sign(s) of cheating?

My husband & I have been seprated now for 7 mths. He lives w/ his mom’s house 1 hr away from us ( me & our kids) We have been getting along now for the past 3 wks. I can tell this is thr 1sy time he is trying to work w/me in our marriage. BUT he still isn’t ready to come home yet. Could there be something going on behind my back. Why wouldn’t he not want to come hom and me a family man & a husband?
So can you tell me ANYTHING OF A SIGN OF A MAN CHEATING ON THEIR WIFE??? From the smallest thing to you name it!!
