Heart broken

So i am happly married 20 yr old my husband is 22. We have a beautiful 11 month old son. And a beautiful little girl due in feb 2017. I thought i was pleasing my husband in bed right. Usualy men say something if they dont like doing things. But no i get a wrong text message of my husband telling a friend he has never enjoyed having sex with me. I was not his first. He really was not my first my my first time was forsed.... He told me 2 months ago he wishes i still had my V card when we had sex the first time now i get this message saying i wish my wife was as tight as my other girlfriends. Do you think i could get her to do a 3way and her just watch? It was suppose To be for his best friend. He then messages me its not him texting and it was not ment for me. (He is at work out of town) But like really? I am so hurt i dont even want to do anything sexual with him. I dont know what to do anything or talk to him. Is this normal? Am i being to sensitive? I want to like leave so he can have someone that makes him happy. He says i do make him happy but i dont know anymore . I do love him. But dont want him cheating
