In this line of work this is totally forbiden and yet I did it?

In my line of work you simply cannot fall in lovee and you cannot get close to the people you work with. Take the pay and next. But he was way different than others. He was a CEO, early 40s, polite, charmin, confident. he came to me because he was overwhelmed with everything. meetings, business deals and had no time for his 3 kids. he was also upset that his wife is not listening to him. He loves talking about himself. At first it was fine. I was paid to do it. But I developed strong feelings and he told me at one point I am the only person in his life he can trust. It lasted 8 months.

I am 30, so I should not be this naive. At least I found a new job and its a normal one. But I cannot ferget him. He was one of a kind and I still check his socials daily. its been almost a year. It was me who ended it because I told him I have feelings. He was very upset at first and reacted badly but then he moved on. How do I do the same? He was special
