I really don't think it's you,I think it's him.And I will probably get backlash for saying this but I think it's a guy thing.

My husband does the same thing.And it's really hurtful to me because I feel like I am not worth listening to or something.Like I am so taken for granted than he simply doesn't care what I am saying.Of course he says he loves me,and I believe he does,but I sure don't like that he does this.

I am curious how your husbands tests will turn out.I hope everything turns out good.My husband has had all kinds of tests done and I feel he has 'selective hearing',meaning he just hears what he chooses to and tunes me out most of the time.
