Man that sounds like a little problem but it's probably not a big deal at all. I met this girl and I hung out with her 2 times. She had to go away for 10 days to Hong Kong for a wedding. I guess she was into me but she said I know you're going to forget about me... Maybe if you say something like, "I hope I don't forget about you when you go away." She'll still have you in her mind. and make it like YOU are the one that will forget HER not the other way around. That way she will still want to speak to you instead of being forgotten. You can probably add something to the quote I used to suite your situation but I think that's a starter...
When my girl went away I talked to her like 1 time but it's kind of hard to do so eventually we stopped talking then waited a few days after she got home and we started talking again and if you are nervous that she forgot about you or something try to go back to something like oh wow (__
something_____) just reminded me that you were back. And always remember that she's just another fish in the sea. Don't give up.
If you actually use that one let me know how it goes and if you would like some advice. Always here to help.
