😭my husband is cheating on me!!😭

my husband is cheating on me. he says he is in love with her. we have been married for 5 years and the woman he is wanting to leave me for is married with a child. he is going to give up everything for her. I'm so hurt right now. I just need some incouragement and advice. this woman i swear is evil bc she keeps telling and doing so many lies to save face. but she also is trying to convince her husband that nothing is going on anymore. this is so screwed up.
