My point is this -- if she wants legal separation, you really can't stop her. You can tell her it's not what you want, but that's about it. If you fight her or try to convince her with words, you will only assure her that it is the right thing to do.
You cannot talk someone into wanting to stay together with you.
On the other hand, if you proceed in getting your green card, completing school, holding a job, and are generally happy and fun to be with, one of two things may happen: - she may get interested again and decide to come around, or - you may find that she isn't worth waiting for
And today, nobody, not you, not her, nor anyone on this board can tell you what will happen, or even which option is the better option.
So your choice is to resist and lament that which you cannot control, or to choke down the sh!t sandwich you got for dinner, and then move on to find a better looking dessert table.
In the last few weeks you seem to have broken your total dependency on her, and that is a very, very good start. You're doing all the right things, Complex, now you just have to feel it.
