He's being cruel to convince himself that he had enough reason to do it and is looking for your approval so that he can sleep better at night... Trust me. I'm going through very similar in this exact moment...
I've heard so many bad things about myself that I legit asked myself why the hell she was with me to begin with, but the reason for this is selfish... Just so that they may turn around and say "yep, see how bad he/she was to me, I'm doing a good thing by dumping them"... Cut contact, you don't need this stuff in your head, you're a good person, you were true to the relationship... Their loss... Just tell him to start being respectful or to text someone else who'll take it because you won't... Demand some respect, that's good advice, I'll do the same ;)

... Three months in found out he was talking to someone else...
This doesn't sound to me like a guy who is ready nor raring for a Real relationship, Cat1290. He is speaking to another, Lord only knows what about, and making you Now feel-------I considered it cheating.
You are so right here, dear, it Is a form of being a cheat sheet, and with it, you can't trust him again. Now he is playing head and heart games with you but don't fall for it. He probably just wants a Friends with benefits fling thing now and No-----He is Not ready for a long term relationship.
He is sore loser, wants to make you take the fall, this coward and once his 'Single life stuff' would have to come to end, he is leaving you, this cocky rooster, with egg on your face and to take the blame for his Guilt ridden actions.
Stay clear, move on. I don't trust him nor would even want this schmo as a friend indeed.. no Need.
Good luck. xx
