Ok my experience with this. First, let me say that I only hobby when I am between girlfriends, never when I am attached. I get with the occasional provider when I am single because it keeps me from getting into a relationship with someone with whom I know I would not be a good long-term fit just because I am lonely or so that I can have sex.
So I met a local provider who has since mostly moved on to a different city. We hit it off in bed and personally, and she called and asked me if I would like to go see a movie. This started a couple of months of us dating, calling each other boyfriend/girlfriend, etc. I was fine with what she did, although her expectation based on previous experience was that I would eventually tire of it and want her to quit. It turns out that she did not care for what she does for a living, but it was easier than actually having a normal job: better hours and pay than anything else she could do without any degree or special skills. What she was shooting for was one rich client who would simply pay for her to be off of the market, or ideally, someone serious who was not a client who would pay her way and let he not work again. I had no problem with her escorting, but I would not have minded if she had quit and done something else either. What I was not going to do was offer to support someone that I had just met, although I did help her out on a few occasions, supposed loans for which I doubt I will ever be repaid. So as long as she did her job, she was going to be fundamentally unhappy, I cannot be in a relationship with a woman who has something in her life that makes her unhappy and is not going to change any time soon because she is unwilling to do anything about it, whether that issue is her weight, her job, etc.
So could it work? Maybe. If she truly enjoys what she does or is willing to take a straight job if she does not, then it could work. But I am cannot be the reason for that change. Sure, if I am in a relationship with a woman and she wants to have my child and make a life with me, then I would be willing to devote all of my financial resources towards our family. But now the situation is no different than it is with any other woman. Being a provider would have to be incidental to everything else in one of the two ways that I describe above.
