It depends on the person. I can offer my perspective. Even if I've had bad experiences, being an escort actually gave me faith in men because I met a lot of men who treat me very well and who are trustworthy. I also see shades of grey in people's behavior.. nobody is a total asshole or a perfect angel and that's okay.
But you have to make the difference between a client provider relationship and a real romantic relationship. They're not the same. I still feel the desire to have a romantic partner personally and I don't expect them to act the same way as my clients.
What has changed is that boundaries are more and more important to me no matter what kind of relationship. Being an escort in a way have me an opportunity to practice healthy boundaries. I see certain red flags a lot more easily now. But I also see green flags more easily.

I won't expand on this too much..
My friendships and relationships with other people are much healthier now tho.
