Yes I've dated someone who had a foot fetish and no it was definitely not grounds for breaking up. It was really a lot of fun, to be honest. My feet were never something I considered particularly attractive before but his extra attention made me feel sexy in a way I'd never expected I would. I liked feeling sexy, I liked seeing him enjoy himself and I liked facilitating that enjoyment. All positives.

You never know, I realllly hated my feet being touched before I met my ex. I'm insanely ticklish and even the slightest brush would make me flinch. But we worked up to it slowly, he would put his hands on my calves and really gently and slowly massage his way down to my feet and just hold them so I could get used to it. It took a while but eventually I became somewhat desensitized. I'd still jump if he went for them really directly, but it became much less of an issue as time went on. If you'd asked me before I met him, I would've said foot play was totally out of the question but clearly I was wrong, haha. Not to say that your situation is the same, though.

I've dated someone with one. I dealt with it, I didn't mind his fascination with mine. Atleast I know mine are attractive now! LOL
