Good for you, girl...I think that if you let your H take the reigns of this M by, talking less, stop and listen to him, not interjecting into his talking, letting go of the "need" to fill every pause of silence with chit chat, you will find that your H doesn't have a communication problem at all...you just don't let him, thus, he "tunes" you out.
As I said before, Whatisis repeated as the male response, men don't like endless chatter...never will.
Each time you're together, let him run the show...silence is golden...even if it seems ackward that no one is speaking, don't speak...let him be forced to break the lull in the conversation. Just sit back, looking coy, mysterious and alluring...
You CAN do this...he needs to come back b/c he wants to and finds you changed into someone who nurtures him...not walks over him....
