Never felt so alone.

When I had my daughter 6 years ago I was alone throughout my whole pregnancy. This time around I was promised I would not have this again. But my partner has been nothing but horrible and disrespectful toward me. There was an allegation made that I smacked my child. Rather than support me through this malicious rumour he has chosen to pick apart everything I do over analyse everything I say he has literally ruined my pregnancy yet again!!! I hate myself I hate the situation I am scared to be happy I just want it all to go away. I am so low it takes all of my power to not end everything please tell me it will get better. I can't do this any longer
