(sic) it’ s too nice the idea of loosing it all because of her blackmail! What should i do? Resist or let her my social and financial life?
Seriously? You guys need to go back to grammar school, but I’m giving you a pass on this one G cause you are using a translation service I see. That aside, the decision is ultimately yours to make G. No one can tell you what you should or shouldn’t do. If you want to resist because you get off on her trying to take more then go with that. If you want to learn what it’s like to give yourself over and let her run your financial and social life, again, go ahead. You’ve read enough on this site I’m sure, that you know the dangers of doing what you’re doing.
As I always say, if it feels good, do it. If it doesn’t, and that includes regret afterward, then don’t. It’s really that simple.
