Coping with Becoming a Single Mom

Ladies how do you cope with the end of a long-term relationship? He left me for another woman that he been cheating on me with for sometime. I found out that he even had been taking our 3 year old daughter around this woman. I’m currently 31 weeks pregnant with our second daughter. Our daughters could possibly have different last names. This entire thing has been so hard on me. I never imagine having to give birth by myself and raise our girls by myself. The stress has caused me to develop preeclampsia and I will most likely have a preterm delivery. I’ve honestly been crying for 3 weeks now. I’ve only felt this type of pain before once before, and that was when I lost my mom. I could really use some advice and encouraging words.
