Wrong or right? Sister mad I want to move....

Okay so I have never been away from my immediate family, we live separately but till in the same city. So we are very close.

I live in a small city, with no fun family activities or job opportunities. It's hot as heck and just a miserable place to live full of druggies.

I have been wanting to move to a different city or state for a while now. I recently posted on my Instagram story that I want to start looking into moving.

I think it would be better for my son and for our little family. We can do more things together and he can be raised in a better, happier place.

Anyways my sister got so mad, saying that I'm going to abandon my family if I move. And went on to say hurtful things like I've changed since getting with my babies dad, that I would never leave the family before I got with him. And that she might as well not see her nephew because the more she is with him the more hard it would be on her when we move...

I feel bad, I dont want to take my son away from my other family members, but I also have to think about what's best for my family (my son, husband and me) she has a way of making me feel guilty but I dont think I'm wrong...

I just need opinions. Do you ladies think I should stay to make everyone else happy, or move to make my little family happy and gives us a better life? I feel like it's a no brainer but my sister doesnt seem to agree.
