35weeks pregnant leaving my husband

Suspected him of cheating with this one bitch tht he was messaging he told me he stopped. Seen a reord of his phone bill turns out they have been calling each other daily for months and hez denied denied. Even wen i confronted him until I show him the phone records. Im really broken inside i tried to make it work i stopped going through his phone i was willing to start trying to trust him again. Im in a way relieved that im not crazy and the truth is out im just sad for my baby girl both parents wont be together.
