So last night I get a phone call from my mother telling me someone called her and told her that my SO has been cheating on me with someone that is supposed to be a good friend of mine. This person claims the girl he "cheated" with told her about it and showed her messages between them. My mother will not tell me who told her this, she said it will just cause trouble for that person. I don't have any proof other than he said she said but my parents are expecting me to divorce my SO, they told me if I didn't then I wasn't apart of their family anymore.. my SO has cheated before but he quit the place he worked and has really changed.. I just don't know what to do.. what to think.. I have a 1 year old and I am currently pregnant with baby #2, I'm so heartbroken. No matter what I do I lose someone I either say goodbye to my family or say goodbye to my husband.. what do I do?

Also I have confronted my husband and the woman he supposedly cheated with, both deny it ever happening and are like me demanding to know who the person is that is running their mouth. I've begged my parents to please tell me who told them this but this person said they want to stay anonymous.. 😭
