Catholics are partial preterists. First, they are Amillennial, meaning they deny a LITERAL 1000 years period (same as full preterists).
Next, they typically interpret the Olivet Discourse as mostly or all fulfilled by the fall of Jerusalem and see Revelation Chapters 1-19 as fulfilled in the 1st century. Parts of Rev 20-22 are viewed as complete and parts are awaiting a final wrap up a long way into the future.
I highly recommend Scott Hahn's 11 tape series on the Catholic view of The End.
Finally, Auntie, I might point out that if you become Catholic you will likely become a strong partial preterist and still will have to deal with Paul's theology of Resurrection where he reckons the victory of Resurrection as tied to the end of the Mosaic Covenant Age and NOT Christ's Covenant Age.
1 Cor 15:54-56
"then shall be brought to pass the word that hath been written, 'The Death was swallowed up -- to victory; Where, O Death, is thy sting? Where, O HADES is thy victory?' And the sting of the death is sin, AND THE POWER OF SIN IS THE LAW
Paul clearly sees the victory of resurrection coming at the end of the Old Testamental period, which is why he believed that his generation would live until that event (Paul says "WE who are alive and remain until the coming of the Lord... -- 1 Thess 4:15) and proclaims it was ABOUT TO happen in Acts:
Acts 24:15
"there is ABOUT TO BE a rising again of the dead, both of righteous and unrighteous"
Acts 17:31
because He did set a day in which He is ABOUT TO judge the world in righteousness
2 Timothy 4:1
I do fully testify, then, before God, and the Lord Jesus Christ, who IS ABOUT TO JUDGE the living and dead at his manifestation
Paul does NOT believe those events were thousands of years into the future, but rather were to transpire with the passing away of the Old Covenant universe in his own generation.
