The one thing your relationship could use more of is affection.
Affection is a good thing for your relationship.
A very good thing.
Hand holding, over the shoulder kisses on the cheek, long hugs, and cuddling are key for connection, love, and attachment to develop in your relationship.
So instead of possibly being impatient, stressed, and grouchy with each other, just hold each other a little tighter, and try this advice from Lori Lowe,
“Research consistently shows that touching more creates a stronger bond by releasing oxytocin. Hold hands, rub shoulders, hug, kiss, give high-fives or even fist-bumps or bottom pats. When you give a quick hug or kiss, try to lengthen it to at least 5 or 10 seconds for more effective results!” – Lori Lowe, MA (here)
Or, instead of just 5 or 10 seconds, why not try 60? That is what Laura Marshall suggests.
