It's hard for her to miss you when you are up her ass all the time.
Part of a healthy romantic relationship is enjoying quality time spent together, but when a man gives up everything and makes his woman his world the relationship eventually falls apart because while she wants you to be happy, being responsible for your happiness is to heavy a burden for her to carry.
Do both you and her a favor. Get out of the house without her and create a life for yourself worth sharing with her. She will appreciate having some time to herself and when you return, she will welcome you back home.
