Why would a guy purposely mistreat probably the best woman he’s come across in life?

So this guy who I’ve been dating or talking to for over a month who asked me to be his girlfriend and said he loved me, said it was a lie and he never meant it, and told me he didn’t wish me well in life when I said it would be the last time we see each other for his bad behavior (communication, anger and drinking, etc)- texted me “Hello” a few days after the incident which I of course ignored. I loved him and supported him 100% but couldn’t take the stress and drama. He has multiple women he can use for “one thing” so why would he waste his time contacting me when he’s known those women longer and it’s a sure thing they will give him what he wants and I clearly won’t anymore because of his bad behavior and we keep having problems and I told him it would be the last time he will me? He clearly stated I was nothing to him so I don’t get his deal (also half the time we were together nothing happened and we just hung out by the way even went a few places and he helped me a few times even took off from work once when I was sick which he claims meant nothing and any guy can do). The other girls he has access to are pretty so he can contact them. Also he knows I have medical conditions that make that hard for me and I’m sure the other girls don’t have those problems and wouldn't challenge him. I had his back and he said he wanted me by his side... I even was there when he was have a medical emergency one night and he held my hand (related to his drinking). I never judged him and accepted him but it’s like he treated me bad instead of like an ally. There are women who would spill his dirty secrets, steal his money that he leaves around, and not try to support him or accept his child.
