Feeling like a single mom

It sucks to be in a relationship but just feel like I'm a single mom.. He's always busy trying to please everyone Else.. I'm sick of when I'm actually off work I am just sitting around bored just feeling the need for some attention, care and love.... our daughter tells me that I'm her favorite parent because I'm the only one who spends time, she asks all the time why it's just me and her doing stuff, asks me if daddy will ever have time for us... I am just at a loss. I've never felt so desperate for a little time and attention :(
