Why do guys chase temporary girls?

A guy from my church was interested and I turned him down and later ruined his reputation because he slandered me after I rejected him out of anger he spent his gas money giving me rides home and did not get rewarded with a relationship.

Later a guy interviewed him about it and found out he wanted to sleep with me for 2 weeks and break up but I wasn’t interested in even a date and he got angry at me for wasting his time and started trashing my reputation and dating and sleeping with other women.

Why do guys ruin girls lives for 2 weeks of experience? And I get treated like trash for rejecting him and not participating?
