I've recently met a person I am strongly attracted to.  

They rejected the idea of a date because "at the moment [they're] not emotionally available", since they recently came out of a long term relationship. The breakup seems to have been caused by distance (as in "an ocean and half a continent").  

Because of this, I have the impression that they are afraid of ending up again in a "distance" situation. And me being from Europe, and them from the US, is not helping in this regard.

I would like to communicate to them that, in the case we would be together, and they would decide to go back to the US, I would be up to relocate with them.

Is it possible to communicate this without sounding "stalkerish"? (i.e.: I'd like to avoid sounding like "if you move, I'll follow you no matter what", since if I would not be in a relationship, I'm very happy to live in the EU and I don't think I would move in the US by myself. I could see myself visiting the US, though. We currently both live in the EU, but they might move back in the US in the next year/few years)
