Billionaire Ex-husband's Baby

Ethan is a 27 year old billionaire and an extremely awful husband to his 24 year old wife, Olivia.

He only ever puts his interests before hers but above all else, his mother's interests take priority, so much that when she demands that he should divorce Olivia because she's been a useless addition to the family, he agrees to it.

After the divorce, it's meant to mark a new beginning, but Olivia finds out she's pregnant, giving rise to a possible second chance for their relationship.

But with Ethan's mother standing in the way because she deeply hates Olivia, can he learn to stand up to her and put Olivia and their baby first? Or is he just too scared to go against his mother and lose his chance of inheriting all she has?
