I am not looking for a return on my investment here. I only want what we always had, even before I helped support her. If you read my OP I did talk about trying to keep the spark alive, which has nothing to do with buying her anything. She is unresponsive, as I said before.
Why is it that whenever anybody is upfront and honest about money people respond like they're trying to buy people? I have worked my ass off and being successful is something I am proud of. I spend a lot of money, and live a great lifestyle, and it affects the way people relate to me. That does not mean I am using my money to buy people or sex, believe me I could if I wanted to. But the reality is there, people do stupid things for money and security. And when you are the one who can provide it, people will deceive and mislead you, to gain access to it.
You may be the one ignoring reality if you think you are STILL doing EVERYTHING you did during the dating phase of the relationship. So, my advice is to closely examine your own actions be be critical of yourself. If she were so dead set on the fabulous lifestyle YOU have afforded her, why wouldn't she continue to have sex with you THE WAY YOU want it? Perhaps your materialistic lifestyle is not so fabulous in her eyes. Again, if you are serious about maintaining a good relationship with this woman, find out what she wants and stop thinking about all that you think she needed and you gave to her.
