Definitely cheating. Similar story happened with me, he had mood swings, anger, irritability, he got really drunk a couple times and would say things like, "I don't know why you're with me", seemingly for no good reason.
I was kind of confused until I checked his phone and found messages that were under a man's name but seemed extremely feminine and a bit too flirty in nature.
I also called the number and a female answered. Confronted him, he denied it and had a great cover-up story which I pretty much believed, but still had a nagging gut feeling that something was off.
Then, a couple weeks later, I found the number again by chance and called it, and got a girl's answering machine. So I confronted him again and he knew he was busted, admitted he had been texting this girl behind my back for a few weeks, but said they never had any physical contact.

He is obviously texting another girl with "sweet dreams". Is this your boyfriend or husband? If I was in a serious relationship I would need to find out and would probably hire a private investigator if it was my husband. He is definitely disrespecting your realationship! Hope it works out..
