I need to inform that I never in my life thought I’d get feelings for a married man?

We work together at the same department literally almost see each other every day, and I believe it’s the way he approached me from day one, he is a good looking and my type so that makes it even worse but that’s not the problem I think it’s the way he approached me and came across me as a very friendly nice guy, I didn’t develop feelings for him at the beginning maybe few months past and I still blame him, he would start asking me if I thought he was attractive I brought his wife up right away than once he mentioned how his wife thinks his ugly and he wanted to see my reaction so I have every right to say it’s his fault I started kinda feeling bad for him bc like I said he was nice to me from day one and it kinda got to me I still shrugged him off bc I know his married, than I know I’m not the only one feeling down way bc other coworkers start notching that he might have a crush on me type of thing to this point, I can say my feelings might not be as strong but when I get to work it comes back bc I see him, what should I do I just don’t want to me waisting my time on something that will not benefit me in life, the thing is I’ve been single for a few years and I’ve had desire to patiently wait for the right man (single) and I’ve been preparing myself until he came along and now I feel lost and confused am I overthinking?
