You know, I also knew a former thera who went through almost the same situation as you, but she kept coming back when she was in need or having financial issues.
Her story is almost similar to yours, so you're not alone in this. Her client/bf, introduced her to a luxurious lifestyle here and overseas. He gave her things she had never experienced before in her life. She fell deeply in love with him, and eventually, the client/bf reconciled with his legal wife. I won't go into the details, though.
I know that deep down, she still loves the guy very much. Her words and actions may say otherwise, but my gut feeling tells me that she still has feelings for him.
A man's instincts can sometimes pick up on things that a woman tries to hide. Often, tends to ignore the signs because his heart takes over his mind. When emotions are involved, it can be difficult to think clearly and make decisions based on logic rather than feelings.
