Separating

I'm afraid my husband and I are going down the road of separating. Our friends are all his friends and I have no family around either. Anyone separate with literally no support system? How did you survive? Any other advice for getting everything in order?

Among many other issues if I say I'm overwhelmed with mommyhood I get it what did you expect? It to be easy? And then he blames me saying he never wanted kids to begin with but he actively tried for them with me and knew when we got together and married kids were always a part of the deal for me. So the kids are my responsibility and I should be able to care for them without complaining and manage a house and work full time. I'm just really sad it's coming to this
