Relationship

Hi ladies. This is probably not the place to vent, delete if not allowed. But I am 24 weeks pregnant, and my now ex boyfriend has been there through out my pregnancy. But this girl messaged me 2 nights ago at 3 am showing me a screenshot of my bf telling her “ I get drunk and I just think about the times I would make you mine and give you dick” I’m sorry about the language. I felt so disappointed, and broke up with him immediately. I told him if he needed anything he had my number just in case for anything for the baby. I blocked him on social media. He didn’t want to give me his Facebook password, he just turned on his location. I talked to my mom about it and she said it was okay if I decided to let it go since we have a baby on the way. But I feel so betrayed, disappointed, and disgusted. I don’t know what to do. Have any of you girls gone through the same thing? It feels horrible. I feel so broken.
