does the father want something to do with the baby at all?

If he does then I think you should stay put. I personally would attempt some reconnection with the father (to see his child) once the bub is born anyhow. My ex (ashtons father) was not interested, they have since had some visits and he loves him and wants to be involved in his life. I can't deny him or Ashton that.

Also I think having support is necesary, especially as this is your first. Family, friends etc are VERY important. Raising a baby is a lot harder than you think, let alone doing it in a country where you have no support and know noone.
