how do you fight the loneliness...

as a stay at home mom, how do you keep from getting lonely? I dont have any friends (lots of reasons but main one is location.) we live out in the country so there is not a lot of things for a pregnant lady to do. nor are there a lot of mom groups in a 50 mile radius. I have a 4 year old and a 7m old and another one on the way. on the weekends when i wanna take the kids and get out of the house for a while. hubby never wants to go. I get that he has been working all week and just wants to relax at home, but I cant do it by myself. I havent left the house in weeks except to go grocery shopping. really starting to feel low.
