husband wants to leave me

Tabitha • Pregnant
I need help ladies. Been struggling for weeks with distant unloving husband. Been together 8 years married for 2 years. I thought this was a bump in the road with him not coping with a hard pregnancy - we lost a twin early on but not have healthy boy on the way but I've had other complications.... anyway he's now saying he doesn't want to be with me but wants the baby still. How can I cope on my own ... anyway single ladies or recently broken up can help me. Don't know how I Can do this on my own?! When we planned this together. I have tried everything to make this week and now have 4 weeks until I'm due....
UPDATE - he's been sleeping with my best friends it's over I'm officially on my own.  Just me n my baby now
