Dear Woman Alive,

My husband and l have been married for two years now we have two kids and third one on the way. l found out early last year a week before our anniversary that he is cheating and found a sex video with his mistress. Because l love him l forgave him and moved on though it was hard. In July l found that l was pregnant and things changed until October when l found that he is still with that lady. He found her a job at his work place. l confronted my husband and he said the lady is threatening to post the video on social media. l don’t know if it’s true, but since October he doesn’t touch me, we are just like room mates and l feel I am going through the pregnancy alone. It’s so painful and my pregnancy has complications. I am expecting my baby next month. What should I do in this situation please help me.
