The thing is, I cannot describe every details in an article, which leads to such comments. And I'm okay with that, because you are totally entitled to your opinion.
That guy was flakey, inconsistent, closed-off and immature on many levels. And he was incredibly selfish and borderline controlling; all he cared about was himself , his feelings and what he wanted. Not to mention, he has disattachment issues and he couldn't function properly in a relationship - frankly speaking, he didn't even know what a relationship should look like.
Not only I asked about his feelings and what he thinks on many topics, I actually gave him a few more chances to date me in the future. Because I was understanding on his attitude, lack of emotional maturity and also several mental issues like ADHD and others. However, at some point you realize that the person doesn't deserve any second chances, and even the ones you gave them were too much. I'm very empathetic and understanding, but I have boundaries too.
Him freaking out about not having control about the proposal was one of the few red flags in the beginning of me meeting him.
