AKA, you're willing to overlook red flags to FORNICATE with a woman.
As someone here said already, if you want to "help victims", there are plenty of legit channels to do that. Easiest way to do this is through your church (Preferably Catholic or Orthodox, not prot or some cult as your ex gf was)
I used to think this way too, I "felt bad" for broken women and wanted to "help them". But when I woke up and took the God Pill over a year ago, I realized that all I wanted was easy sex/fornicate with these women because broken women are extremely easy and have a high libido(because of past abuse). Please, be truthful with yourself and realize you don't want to help people...you just want to fulfill your lust. You are a complete slave to your passions and you are rationalizing your slavery by saying how "bad" you feel for some girls. Admit to yourself that you are just looking for easy sex because Sex for you is not easy to come by. When the chance to fornicate does come to you, especially in the form of a steady stream of a "relationship, aka a fornication partner, you become that person's slave, but most of all, you become a slave to sin...
Before I took the God Pill I played the role of the "older guy" in a similar story, but due to my already fortified pro-life stance sex never happened. So I just enjoyed the attention and company of a young woman who obviously wasn't single, but I avoided buying her gifts, as the transaction wasn't based on physical intimacy.
However once she figured me out, she quickly moved on. So I can confirm: It's not the "older guy" who desperately wants to get intimate, it's her to gain control. And I can also confirm: Leaving the bedroom out of the story removed 90 % of the hassle. Back then I was just doing what I thought was to the most sensible thing to do with a woman at peak fertility, reducing the probability of an abortion to zero. The notion of sin wasn't even known to me.
