Should i stay or go?...?

I have been dating my bf for almost 4mths, and everything seems great...he is working out of state, but coming home to visit his mom for mothers day..he wants to take me to meet her but there is too much family drama going on. He is the oldest so its tradition that he takes over the house etc. I would like to go but then I don't wanna see his bro or sis giving him a hard time asking for money for this and that, usually its a "want" thing and not need. I understand helping his mother and his lil sister, but his other sis is almost out of highschool and the bro is out of the house..I am always there for him to console him and give him advice and not have them take advantage of him esp monetary. He is barely making money and gets frustrated with his job and then his fam calling him when he gets paid for $100 here and there, and his sis wanted 200 for her bday and gas for the month. Sorry but I was happy with 20 and a happy birthday message. She is gonna be 18, just had a miscarriage and quit her job, (unexpected preg) and then she wants to celebrate her bday? Why not get her job back instead? It stresses me that he works so hard for his money that he barely is making it. and to see him stress cause they are constantly calling him for money. So anyways, he wants to take me, but then he doesn't cause he can handle his family and he knows I will be upset seeing them asking for unnecessary things. So should i be by his side and go or stay home? I live about 6 hrs from his hometown so its not like I can go visit for a day and leave. And he is only staying for about 5 days. Any suggestions please??
