Should I stay or should I go?

I felt compelled last fall to try and minimize the amount of possessions and take the opportunity to visit and maybe even live on another continent. I am now here in the USA and having a hard time determining whether I should stay or not. I have a boyfriend here but as he is obviously a mirror in which I reflect my own deficiency, there are things about him that disturb me to a degree in which I have a hard time opening my heart fully to him. At least I think that is the reason. It could also be that we are not truly connected or compatible the way I would hope to. On the other hand maybe I have false beliefs regarding relationships and love. All the changes and the pressure to adapt, open up and accept a life devoid of all the things I am used to is terribly difficult. I have to make a decision very soon, as my visa is running up and measures have to be taken in case I decide to stay. My companion is going through a very tough time in his life and so I feel quite overwhelmed by his difficulties, but also want to be loyal and help if I can (so far I haven't done well in supporting him though as I haven't feel I've had enough support myself). These include a lack of income which could also mean that an extension of my visa might be impossible to put into practice (as it would be very expensive). I also dread having to return to my old life, as there is nothing there for me other than my belongings and my pets. A third alternative but doesn't seem that it would work out either. Since I am here now, should I just take the leap as well as the consequences of such a choice? I realize no one might be able to give me any advice but thought I'd try and see if any ideas creep up anyway. My bf asks me to listen to my heart, but my heart is confused. I cry very often - maybe because I am scared of each alternative but maybe also because I am attached to this man and feel that he needs me to get his life on better track. Despite our arguments based in fear of not being seen and accepted for who we are, I have apparently been a positive influence in his life. I am just not sure he will be able to open up to my spiritual view of life and whether that is a problem or not. I am of course fond of him and hope to feel more in time. I have scribbled a couple of blogs on the subject for anyone who is interested but mainly in order to sort out my own thoughts.
