8 year age difference but it seems like not too bad.

If he’s 33 (very well established, financially well off and career is set) and im 25 just starting my actual career could it work? I feel like 8 years older isn’t too bad but idk. I always hear that these relationships benefit the man more. I obviously am not paying for anything and do want commitment. Any warnings or advice before I get too deep? Why exactly is dating older men within 10 years bad?
