I’m able to relate to the OP. The guy shouldn’t feel the least bit poor.
The “shut up, pull it up, and proceed” statements is dismaying. Activities have consequences. Unless you wish to be thought of as a slut, do you know what? You shouldn’t being one. However the actual concern isn’t the girl previous promiscuity. It’s their deceit. She deceived this person for things she need. That’s OK? In order to those who say, “Well, everybody else sits about their past”. NO! THEY DON’T! I don’t!
I have already been and stay in an identical scenario once the OP.
