help!!!!!!!

Summer
I'm a single mom of two and I recently found out that I'm pregnant again.,instead of being excited I'm actually nervous scared & confused..the father of my child is basically a man whore whom I really don't see a future with at all..he basically says the typical "I'm going to be there for the baby" thing but is he really going to support my baby? Who knows...I'm so against abortions but in my situation can I handle being a single mother yet again to a third child..idk what to do but what ever choice I make I need to make it fast😢I just don't understand why God gave me the life of a single mom instead of being a wife😔
