If this girl really cares about you then she's going to care what you think.

I would say the worst approach would be for you to suggest she should leave the LCM so that you two can be together.

Probably what you should tell her is that you care a lot about her (love her) but you just cannot see yourself in the LCM. You can go on to tell her why but do it in a way to show you care about her and her future. In other words, be selfless.

Then you just have to wait to see how she responds, and live with it.

But I'm afraid the practical lesson of this situation is don't fall in love with people in groups like the LCM.
