At this stage in life, the dating pool has its share of divorced people.  And, chances are good that some of these divorces were the result of infidelity.   And with any infidelity, you always have to wonder the cause.

Were their needs not being met at home?  Did it just happen by circumstances?   Were they looking for an upgrade?

Of the above, unmet needs is probably the biggest concern.  If the needs of the last marriage were not met, will they be met this time around?  That is a tough question to answer.
