Heartbroken while pregnant

C 💕✨
Can anyone who has been left by the father of their baby while pregnant please give me some advice how to make this feel better because I have never been so upset in my life. Our baby was planned and I never seen this coming at all I thought we were happy. He has never treat me bad throughout the relationship and said he will be there for me financially before and after the baby and also be in the baby's life. I cant cope with the thought of him not being in my life when i didnt see a future with anyone else.
