OMG what?!??! So basically you know she's using you so that she can live in America, and you don't want to be back with her but don't want to be alone, and admit that this is an attempt, by you, to get the relationship back together as "prelude to getting married" but you can't stop yourself, and you admit that HER endgame in all of this is to live in the states but not really be with you???
dafuq?
How can you think this is a rekindling of your relationship--the same one you can't believe you 'wasted' time in before--if she sees it as only a "green card" opportunity??? You are both fucking each other over, and worse, you are fucking yourself over on this too. You are admitting that you are both using each other. So do you plan to be intimate again? Please don't go that way, because then there will yet another thing that either you or her will be dependent on that can continue the "relationship" both of you really don't want.
That is essentially the situation.
She might like me, though. She was the one who initiated contact to begin with. We hadn't talked for about four years and then out of the blue on Christmas she contacted me and said that she had been thinking of me. I was on my way to returning to the US though, and was seeing someone else, so I wasn't able to do anything while we were still in the same country, but that's what got the ball rolling on the current situation.
So maybe she does care about me. Maybe I can be with her and not be alone. Maybe I can give her what she wants and she'll love me for that. Maybe I can be with someone and not be alone. Maybe I can have sex and be happy like a normal person. Like everyone else. If I can just make this work, maybe I can stop feeling lonely.
