Married... pregnant... lost right now

Jessica

So I'm new here and need some guidance and support.... I'm 23 weeks pregnant and was told by my Dr my results came back having BV and Trichomoniasis which is an STD. I'm absolutely heartbroken and I feel embarrassed and dirty. She told me to notify my partner and I told her oh that would be my husband. My husband of 10 years. I'm beyond betrayed and devastated. Not to mention unprotected sex. So now I gotta worry about pregnancy too??? I'm lost. I'm hurt. I'm broken. I've already stated to him to move out and I want a divorce. We share 3 children and currently pregnant with #4. Any advice or stories?
