Sitting here crying my eyes out

I'm so hurt right now and u feel completely lost. My husband the love of my life . I really can't believe he did this. Last night my husband went out with his friends. I got a phone call from my friend saying she saw him dancing and leave with a girl. So I was wondering if it was ture he came home and I played it cool so I thought let me check his phone. Behold there was a text message to his friends saying save this number for me under smooth fox.

Now I'm 30 weeks pregnant I'm so hurt that I kicked him out I didn't even care what he had to say. Now I'm sitting here thinking did I do the right thing.

I love him sooo much u don't understand. This hurts sooo much I'm not a jealous wife I don't check his phone tell him what to do. We have a 50/50 relationship. I give him the world. I just don't get why he will do that. Even taking a number in my eyes is cheating am I wrong?

Please help heartbroken wife
