I am 2 months pregnant & feel so alone. Can anyone give me some advice?

I have not long found out that I am 2 months pregnant & when we found out, my partner & I were over the moon & everything was great. However, the relationship between me & my partner over the last few days has been terrible. We have been bickering & arguing & have spent the last 2 nights in separate beds. His attitude has been awful the last couple of days & he has said some really hurtful things to me. I have told him that I am probably more sensitive than normal but that his attidtude is absolutely terrible but he is just saying that it is all me. Now I am feeling so alone because it's as if he doesn't care. I'm also feeling sad because I don't have my mother here with me either (she ped away from braest cancer when I was 8 years old) and a girl always needs her mother but i'm feeling it all the more now that i'm pregnant as i'm not able to share my thoughts and feelings & excitemnet of having a baby but also my troubles & worries too. I am 27 years old & this is my 1st pregnancy.
