Very odd OP. If he was not at home while she’s texting you that he’s outside her house, gives some credence to her claims.
Has he been home since the OW messaged you that she’s pregnant? Have you shown your DP her texts? What does he say?
If you saw devils texts from him to her it’s not likely a bunny boiler but some arrogant selfish woman looking to make you miserable that you’ll kick him out so she can have him
He’s no great prize. These days you can get help and assistance Plus child maintenance. You don’t need him. You don’t need head games. Focus on you and your children.
I went through betrayal like this thankfully in my early 20s. The girl my DP was cheating on me with knew all about me and our baby. Followed us when we moved 4 hours away. This was before mobile phones so I actually confronted her in person.
It hurt like someone physically punched me in the stomach. Drove me almost insane with the physical pain of betrayal, being lied to. Thankfully because texts didn’t exist yet I didn’t ever see or know for sure their discussions about me or meeting up so I can only imagine how that is for you
I got the courage to kick him out. He tried to suggest we all live together or he could go sleep at her place when baby was crying at night. I got the courage to Stay away from him and went to court to get support order. I did eventually move on. Got over it and then met a lovely man. Been married 30 years and had more children plus he took on my first
That OW? She got pregnant and my Ex did the same to her. And the one after that and the one after that. Lost interest after that so I don’t know how many women he’s screwed over (or how many kids he’s sired). I did do one thing that helped me feel a little better. When he cheated on OW and Jeff her after their baby was born, I sent her a congratulations card which read “Congratulations! You got everything you deserve”. I know it’s petty but 34 years later and I’m still happy I did that.
What woman knowingly does that to another? They’re welcome to the cheating bastard . Kick him out. Focus on you and your dc. You will survive and it will get better.
