Emotional

I'm currently 16 wks and 1 day pregnant. My partner or ex partner walked out 2 days ago after having an argument after being together for a year and a half. He's now blocked me on everything so no way of contacting him about the baby. This will be his first child but my 4th. He wanted a child so bad. He doesn't understand my hormones and kept saying you can keep blaming hormones. I told him how I didn't want to be a single mum again, I didn't want to feel like I'm on my own through the pregnancy but I agreed to have a child with him. He said he would never do that to me. I also told him what I can be like while being pregnant and he said he would deal with that and it would be worth it in the end. I now feel alone, hurt, upset. I love him to pieces. Family and friends have said to not contact him even by going through his friends and family and just to leave him to do his own thing and he will come back. He will contact me. It's hard because we agreed to have this baby together and he didn't want his child brought up in a broken family. I'm having to do this without him. I don't know where to get support from. Do I leave him to it and see if he contacts me or do I try and contact him. I just don't know what to. At the moment I can't stop crying, struggling to eat and sleep. I'm trying to take each day as it comes but finding it very difficult. I know it's only been a couple of days.
