Exhausted and broken

I found out husband was cheating on me Last night as I looked at the message from her in her Lingerie talking about I miss you baby and I looked at my family. How ? How could you do that to someone . I just gave him a beautiful daughter I give him the last of my money I took in his son even when he wasn’t biologically mine. And now I can’t stop crying and I have my daughter looking at me. But I can’t stop.My heart is broken because I love this man and his children. I don’t know how I’m going to a hold it together. I’m beyond broken . And my baby has to see and feel my hurt
