My fiance (soon to be ex) cheated.. is it late to start over?

My fiance cheated. I have evidence of hotel bills and his own voice admitting it to someone else. I'm about to break off the engagement. It wasn't a ONS. Apparently it's been going on for a year, a whole damn YEAR.

Is it late to start over at this point. I'm 26 years old. It sucks that I've wasted 4 years of my time with him, get engaged and have to sadly cancel everything. I don't want to but I can't be with a cheater. I don't trust him at all.

I haven't confronted about it yet. I just found out recently this week, had been busy with work and had to do several errands. It's overwhelming.
