My Pastor Made Me Know That My Husband Is Cheating On Me

I am 26 years old and a mother of two. I have been married for 3 years now. But ever since I got married, there has been a lot of hardship.

My mother has been the one supporting my home financially. Few months after I gave birth to my first daughter, my husband started cheating on me. I was heartbroken but I forgave him and we moved on but still in serious hardship.I mean real hardship. But just Last Sunday, we were in church and our pastor called him out saying, "Oga, your wife has suffered a lot and you can only progress if you tell her the truth." 

Iwas so curious to know what I was. So when we got home, I begged him to tell me what was going on, only to find out that another woman has a child for my husband almost a year ago. I am heart broken.

This is a man that can't feed his kids three times a day. But he still goes out to cheat not minding that we are suffering. I need your advice on what to do please I am so heart broken.
