No, having a literal history of cheating is just inexcusable, regardless of gender. Break up if it's a shitty relationship, or just don't get in a monogamous relationship in the first place. It's 2026, open relationships are a thing, or you can be single and fuck as many people as you want, etc. It's the lying and doing it behind your trusting partner's back that's the problem, not the polygamy.

And if you want an open relationship and your potential future partner doesn't... Well maybe find someone who shares your views instead of cheating on someone who doesn't?
