It can be as simple as using deodorant, shaving or trimming your nose hair (not in front of Her please.) Be attractive to Her even if you don’t have to go to work or anywhere else. Be neat and presentable even at home. When you were courting you made sure that She saw you as someone She would like to spend time with, you were clean, smelled good and wanted to impress Her. Don’t let that just fall by the wayside now that you are together.
