Thanks! You definitely sound like you've been down this road many times before. My sweetie is definitely not a "pro" but more like your second description. Out of your 3 outcomes, none of them seem likely. It's definitely not #3. I know it's hard for many to believe but there are women in this business that are not gold diggers and she's one of them. She's had so many opportunities to get "help" from me but she declines. She's a very proud and simple woman. She has a strong passion for the Arts (e.g. music, drawing, etc.). Her passion hardly costs anything and consumes all her free time (thus, she doesn't need much money to be happy). Because she's so proud and stubborn, I don't think #1 would happen either. Realistically, based on the advice from most here, I'll try to slowly distance myself and build rapport with other MPAs to help take the pain away (and no, I definitely won't fall into this emotional trap again).
Things would only get complicated if she actually had very strong feelings for me and did all she could to not lose me. If this were to happen, then your #2 could definitely come into play and like you said, I could wake up one day and truly regret it. However, because of her pride and belief system, this is unlikely as well. To give you an example, I was telling her that I was losing money in the stock market recently. She then proceeds to tell me a story how she once lost almost all her savings because of a bad investment that someone persuaded her to get into. I said you must have been so pissed. But no...she said by accepting that loss, it just means she avoided something even worse from happening (like loss of someone close to her). If she eventually lost me for good, she would be hurt but would just accept it and rationalize it by convincing herself that fate has a better outcome for her down the road. This is her mentality and makes her mentally strong as a rock (which ironically is one of the things I like about her). I must admit her story, as silly as it sounds, has actually helped me get over my own trivial monetary losses too. And she has many similar beliefs that I have applied to my life as well.
Anyways, at some point, when I've properly distanced myself and can handle the outcome, I may take the other gentleman's offer (if it still stands) to see if I was accurate with my assessment of her or just another schmuck. Or maybe I'll just give you her details. Who knows...since you're single, maybe you'll fall for her too and provide her a nice life. In return, you can just let her give me a massage from time to time
