In 1969 a number of saints were removed from the Calendar because there was not enough evidence that they ever existed or had led a life of heroic virtue. Some of those removed: St. Christopher, St. Philomena, St. Barbara of Nicomedia, St. Ursula, St. Dorothy and others. Churches named for these saints were not required to change anything and people were allowed to continue their private devotions to these questionable saints.
In 1969 Valentine and a number of other saints were removed from the Calendar of Saints. He is still considered a saint, however.
I cannot find a complete list of those saints removed from the Calendar of Saints. Actually, they have not been 'decanonized' but were removed from the Calendar because there is very little believable information abut them.

There were about 40 saints removed from the calendar. Here are some of those saints: Saint Christopher Saint Valentine of Rome Saint Ursula Saint Barbara Saint Philomena

There is nothing in scripture nor in tradition that allows that question to be answered. Virtually nothing is known about Saint Valentine and for this reason he was removed from the Calendar of Saints in 1969.
I assume you are referring to St. Catherine of Alexandria. She was one of several saints removed from the Calendar of Saints in 1969 for lack of evidence that she ever existed. However, for some reason Pope John Paul II returned her feast to the Calendar in 2002 as an optional memorial
