Advice please

Me and my husband have been together for 8 years, living together for 3 years, and married 4 months. We have a 9 month old daughter and I’m currently 8 weeks pregnant. This last month has been hard. He started a new job and we started to drift away. He was sneaking around talking to a girl from work but they never did anything other than talk. My husband has been telling me the past two weeks he didn’t know what he wanted and Thursday night he came home and told me he didn’t love me anymore and was numb when it came to me. My heart is crushed. Since then he made the comment to his dad that there was no one else but I stopped it before anything could happen. He has already got him a new house and is moving in today. Every time we talk or meet for or our daughter it’s like a cold shoulder or he acts like we are best friends. I don’t know what to do. My heart is hurting so bad because I love him so much and this is my family. He told me he wanted a divorce. I don’t know what to do I feel so stuck and my heart is hurting so bad. Do you all have any advice?
