I feel that my husband is already emotionally not connected with me anymore does thatt mean he is with someone?

I have prayed to God for signs and answers but most of the time I don't think im reading it right. If God could show me signs that my husband has not and is not seeing someone. I know im not perfect even if my name is perfect or my birthdate add up to fifty or one hundred......does that matter????? I feel taht im only an option for him and that if i dont live up to my duties as a wife then there will be consequences......one of those is to share a time with someone who could be a potential wife for him that he cant see freely because im still here. What if thats only the best i could do and i didn't measure up does that mean the other person waiting could get that time with him??I feel like im only an option, the second one,....the third wheel in th relationship and that because im still alive and not to be hurt my husband has to do it in hiding with the other person he truly deserves......i need your insights please?
