Cheated on and 6 months pregnant

I cant even put in words the rush of emotions I'm feeling right now. I was using my SO's phone when a females name popped up and i saw very very inappropriate text messages that the two exchanged. Getting cheated on sucks, but getting cheated by the man whose child you are currently carrying is a whole nother level of heartbreak. I'm extremely high risk. I've fought and been through so much this pregnancy. Because I'm high risk, I haven't been working and I have nothing, but I'm going to pack up and leave and figure something out. I'm so hurt , I'm so angry , and I feel soo worthless. People don't understand the long lasting effect that cheating has on your SO. I need a hug. 😔
