I dated a rich guy for a while too. Though I didn’t go into the relationship planning to use him for his money, it became blurred when issues started arising and I didn’t stand my ground as much as I should have. So much of this stuff is hard to be aware of, and I wasn’t until I had some hindsight. I didn’t want to lose him partly, I’m sure, because I felt he could take care of me financially. I don’t think it’s inherently bad to seek a financially stable partner but it can get messy to depend on him for that. Glad you found your way out of the relationship!
