My marine

My boyfriend is a marine and there is a high possibility that he could be stationed in japan. I love him more then anything and he says if he goes over there he wants me to go with him and i couldnt imagine not being around him. But I am a giant family person and super close with my whole family. I come from a family with six kids and im scared to be alone. Is it a bad idea to go along with my boyfriend? Has anyone been in this situation(please comment if you have)
