I am having family troubles with my divorced parents.?

I have a issue with my family that I don't know what to do about, my parents are divorced but they have a very weird living arrangement we are still living all together except for my brother that lives with his girl. I am in a dead end job that does not pay enough for me to rent a place on my own, been seriously considering on taking another job to cover the costs but that will kinda pull me apart from my b/f that wants to live with me , he does odd jobs here and there and that is a chance we might be migrating to another country. My Brother alongside with my dad are trying pretty bad to convince me that my b/f is a lowlife and that I shouldn't be with him but the way he acts tells me otherwise plus my mother is coming back from Brazil to sue my dad for alimony and she swore to put him behind bars which makes me feel pretty bad to see both my parents getting at each others throats and using me as a toy to affect each other I just don't wanna get in the crossfire again like it happened when they divorced.The date for her to come back is cutting close and I don't wanna be here to see them fight. My brother is forcing me to go live with my dad and him but in truth I don't quite know what I want yet. I just want peace and I want a way out. Any suggestions to help me get out of this mess.Thank you any comments will be well appreciated
