Something I never thought I would be thinking about!

I’m having the hardest time! I’m a single mom of three and have been dating this guy. We weren’t trying to have a baby or anything but just found out I’m pregnant. He doesn’t want me to have the baby. He told me if I have the baby he will leave me! Well to top it off I just found out he has been cheating with multiple woman! He asked for forgiveness and normally he would be gone already! But I’m still stuck on what to do! I just need some advice for outsiders! I’m having so much anxiety!
