For example we all had dinner at my mothers on Friday evening. We'll be having a conversation, and then he'll just come out with "god I love you" randomly in the middle of the conversation.
He does this quite a lot.
They have been married 7 years so not really in the honeymoon phase.
Of course I'm happy that me sister found someone who clearly adores and loves her but I don't think during group conversations you have to randomly interject with declarations of love for your partner.
