Should i move?

I've been with my guy for four years. I have two children and the youngest is his. He moved back to where he is from originally and wants me to move out there with him. I must say our relationship has been strained doing the "long distance thing" My problem is if I go out there I won't have any blood relatives out there with me. Should I let that stand in the way? I'm not inseparable with any of them, there is my mom but i fell upon hard times and have been staying with her for a very long time, since then our relationship has been strained and might i add i don't feel comfortable living under her roof with my children. The city we live in is very expensive and right now i cannot afford an apartment by myself. My guy lives about 3 hrs away. help! what should i do?
