If she wants to keep acting like a single person, you'd better run away from her.

This. He won't leave Sarah alone, and he will try whatever it takes to get you fired.

So it's better for you and Sarah to find other options.

If you are at some one's house you have to eat whatever meal they invite you. It doesn't matter if you like or not, that meal might be the only one they could afford.

Yeah, just wonder what would be the next lie?

OP: I'm done, I won't lie and sign a child who isn't mine.

GF: But babe, you have to do it. This way my parents will give us all the money.

"I just want her to get better and be a good mother to our son".

She won't.

NTA. When you are invited to some one else's house you have to eat whatever they offer you, 'cause that meal may be the only food they can afford.

NTA. He decided to go behind your back and screw you with another woman. After this, I wouldn't believe any word that comes from his mouth so I wouldn't buy when he said it never got physical.

What else is he hiding from you?

You deserve better, OP. Think about it, if you found out her affair before you married him, would you have forgive him or break up?

He deleted it just because you found out about it.

Thanks to that friend who told you about your (hope to be soon ex) boyfriend.

"He said he just goes to look and ' see who’s on it'"

This is bs. NTA OP, you deserve better.

NTA. If your family ends up getting destroyed it won't be your fault, but your dad's. He had just one job and it was to keep his penis in his pants.

You've been loyal to a woman who treat you well since she came into your life. She will be thankful 'cause you showed her you love and respect her.

Don't buy your father's bs. I don't know the full context but if I was in your shoes and the divorce goes on I'd ask stepmother to stay with her.

OP, tell your sister she can open a business helping people to expose their cheaters SO's.

Sorry OP, hope you can heal.

Now focus on the plan, you have to go nuclear with all of them.

YTA if you don't tell her.

By the way, you deserve to be cheated on by your fiance and to get pregnant and frame you to ruin your life.

Love your self, bro and leave that hoe.

Now, Run away, and don't forget to tell the scumbag's wife.

YTA. Hope he can open his eyes and file divorce first.

Good luck with your addiction, he deserves better.

NTA. Now she knows the risks and if she still wants to be an idiot, then when cancer comes to visit you could remember her "I told you so" and leave.

"I did suggest to my ex that maybe Ethan's biological father could contribute more, but she said he's not in a financial position to help much".

NTA. It's not your problem. You don't owe them nothing. Tell your ex that Ethan can wait 'til his dad can pay for his college.

NTA. Hope you can help your cousin to overcome her problem.

Yup, there's no turning back once you opened your eyes.

Good luck, OP. You'll heal, it's just a matter of time.
