Yesterday I broke up with my girlfriend

Yesterday wasn't a good day because my girfriend and I broken broke up.  She says that I don't spend too much enough (suficiente) time with her, but I'm a full-time student.  I also work and somtimes I´m so too tired like to go out with her. 

I hope we can solve our problems because I really love her.

Thank you for your corrections. :)
