My husband likes to "friend" with my bestfriend

Hi,

We are just married for half years & i'm currently pregnant right now. I might heard as too sensitive might due to my hormone change but i can firmly confirm, i'm not a happy pregnant wife right now.
Even before marriage, i have told my husband to have spaces with my "best friend", let's name her A.

These days, i noticed she keeps calling my husband to go out even during my bedrest period. And when i get mad and asked him to really stay away from her, he was quite furious & thinking i was ridiculous. I was mad and didnt want to talk to him, & he didnt even care & didnt want to talk to me too. He didnt even help me to use medication on my V since i cant see it well due to the bump. He didnt care for me now and I'm disappointed and it makes me thinking i shall just stop love him. Because im afraid if i love him, then i would be sad & i'm afraid it will affect my pregancny. I thought pregnant woman should be happy, shouldnt it? Now my husband doesnt even intend to make me happy. We are just married less than a year.

What should i really do?
