Feel like I was cheated out of a good life

Just found out my SO cheated on me throughout our entire relationship. I feel like I don’t even know him.

He’s been the love of my life for 5 years and we have two kids together.

I’m so sad and feel cheated out of a life I could of had differently.

I love my kids to death. But I would of never had kids unless I knew my SO and I wouldn’t of been together forever.

I had split parents growing up and it was the worst.

My daughter is already having such a horrible time with it and my heart just keeps breaking for her, not to mention I’m still pregnant with my second child and feel like I have nothing to offer him.
