She cheated

My wife cheated. I followed her to her lovers house and they both confessed that the baby my wife just had is not mine. After this I put her out and we have been separate ever since. I filed for divorce but now she wants alimony and is claiming I abandoned her and this illegitimate child and also wants to sue the woman I’m currently dating because she claiming I cheated. How is fair. She abandoned the marriage by cheating and having this baby.Can she sue my current girlfriend

We discuss suing paramours (and what grounds are required to do so) in our article: Infidelity and Alienation of Affection.

As far as the alimony claim goes, if she had an extramarital affair, that can act as a complete bar to a dependent spouse receiving alimony.
