Should I follow my heart, or should I think logically?

I'm in a dilemma. I moved from PA to a rural area in CA with my boyfriend of over two years. This area is hard up for jobs, and it's been almost a year since I've been here, and could not find anything (in any field) in this area nor its surrounding areas. There are better opportunities for me in PA, but I don't want to leave my boyfriend. He has stability here, but my stability lies elsewhere. We both are in tears about leaving one another, since we would be across the country, and know there is no way for us to continue to be a couple. It is hard for me to make a final decision, as no matter where I go, I will be heartbroken. Also, I have yet to find any friends here worth staying for; again, I have found no stability so far, and I don't know if it's fair to continue to live off of my wonderful boyfriend, even though he says it's okay. I want to go back to my friends, family, and opportunities, but it also tears my heart to even think of leaving him here alone. What are your thoughts?
