Here's the story:
We were married for almost 5yrs now.But we went on and off like gf and bf. and when we were off, he always had a gf. Our last reconcilliation, meant a break up for his last gf,but I was cheated,they continued,and the girl got pregnant.We are off now 1month ago,it is only this month that i knew about his infidelity.Because,after our separation,he even accused me that I have another guy,(that was just a comment from fb)he wasn't able to prove. I heard from his friend that he will just try to support our son,but no intentions of coming back to us,because he likes more the 2nd family that he will be having now. I also heard that the girl's family already knew that she is "Kabit", and my in-laws also knew about that. Until now, he doesn't know,that I was already informed of his infidelity, he is much careful about. And I'm just gathering evidences now.
What can I do now? I want to file case against him in the future.
