You might well have identified the cause of the problem (or, more specifically, why it's only just arisen).
Up until recently insurers offered lower premiums to women than to men but now, under an equality ruling, that's illegal. Both sexes must be treated equally. So, if divorced men have to pay higher premiums (because they go out more), women must pay the same premiums (even if they don't go out more). i.e. it's possible that your insurer has been charging divorced men higher premiums for years but, if they wish to continue doing so, they must now also charge divorced women the same premiums.
