Giving up

I think I am about ready to give up. I just don't think I care anymore. I am tired of being lonely, being ignored at home, just being the guy who pays the bills. I am tired of not feeling loved by the woman that I love very much. This morning I tell her I love her before I leave for work and she just kind of mumbles "yeah I love you too" while she is digging for something on the floor. All day yesterday she was doing homework or she was at the grocery store by herself. I am so tired of not knowing what she wants from me.
