is it normal — cord they never cut?

I think my husband loves his mother more than he loves me. He never calls me if we're seperate, but he talks 1 hour facetime with his mother, twice a day, daily. Every single day. He does it regardness, like a normal duty. No, I think their relationship is not like normal. Yes yes you’re right, the cord they never cut. I have, i told him this is not normal. He thinks I am over reacting and he avoid talks about it. He try to call her and love her and kiss her behind me. Kiss his mother behind me. So gross. I just ignore them, they won’t chance. He won't do it. He thinks it is their own way of doing it.
