Advice needed

I have a tough decision to make and unsure on what to do. I have an ex who hardly has his kids (1 x night a fortnight) and I don't really recieve child support from him either.

I am in a position I can start to look at buying a house but if I did it would be in another state. I would love to but I'm also nervous about the decision and I don't know what to do. All friends and family I have spoken to have advised it's the best decision for me but I think I'm scared.

I need advice about it
