Miscarriage

Hi ladies I lost my baby a 3 weeks ago 7+ I was. I still feel very sad and upset about it Cant seem to get close to my partner and I don't feel like I want to be with him atm. He's a big drinker at weekends but now he seems to drink from Wednesday night and it's getting me down I just feel alone I've tried to speak to him about things but that Dosnt help. Any advice would be appreciated
