heart or head decision

boyfriend of 4 years, living together for a year. he treats me well, and does care about me, and i do love him. we want different things im regards to living location. i cinstantly dream and talk about future and consider myself very ambitious. he is quite the opposite and causes alot if head butting. lease is coming to an end and i am nit sure if i compromise more than i already jave and give up more of myself to stick with him because its comfortable or if we should part our own ways.
