I really think perhaps giving each other a bit of "me" time in order to just re-solidify yourselves as who ypu are individually as well as communicating with each other as you have been doing will help solidify the relationship - also, take time out occasionally to have a "date night" with each other and reconnect - just because you're married to each other doesn't mean you can't still "date" each other

You need to de-stress, communicate and find each other and yourselves again.
