Should i stay or should i go?

My bf has a job offer in another state making way more money. We both currently work for the company and HR wants to relocate him and move him up the end of '17. We have been together for almost a year now and had been planning on getting our own apt soon due to us being ready to be with each other and family issues i am having. He of course said he is not going without me. I told him YES i would go with him. I am just nervous... i have a 2yr old and by that time he will be turning 4. And when i leave my parents wont speak to me anymore . they have already told me i better not shack up with him unmarried itll destory my relationship with them... 😥 . should i go?
