Can people change?

Do men change? Can they be better? I’ve been going on and off emotionally with my ex. Some days I feel like it can work again and some days I don’t.

He has such a specific sort of Andrew Tate mindset, like women expire and lose value with sex and men gain value with sex. But he claims he’s a Christian. I said “nowhere in the Bible does it say that women lose value and men gain value because of sex.“ I mean as you know sex is actually a sin outside of marriage. This is tough because he says he wants to change every other day and be better, and I know change isn’t fast it will take a lot of time. But he doesn’t get it.

This is his response to me “I want to live for Jesus Idk why I’m not doing better and last night I was just getting annoyed, I was really tired. I’m sorry for saying you’re childish cause I sure as shit am. I want to be better”. How much of this is BS???? I am going to sound stupid but he was unfaithful to me as he went behind my back to use his ex for her house while he was in another state visiting his military friend, and the reason why I broke up with him was because he was texting another girl to get her hopes up and then drop her because her ego is too big. I unfortunately found their messages from months ago.

I pray to Jesus every night to set me on the right path and I don’t know if I’m overlooking signs and he isn’t on my path or what. I pray to Jesus that my ex will find faith and love on his own without me but I still Love him and it’s hard to just let go without giving it another chance you know?
