That doesn't mean you were dumped, so what she didn't come out before her trip. Your over thinkin it and psyching yourself out. Just relax, and be cool. Send her a message today saying this word for word
You: so.... tell me how much you miss me :p
She may say not at all to be playful, she may say a ton.
If she says not at all then say she's a fibber, and you did miss her till she said that. Usually works, whatever she says just be playful and not so serious, this will actually allow her to miss you more
If she says a ton or something pertaining to that then its simple, just say "that's my girl
can't wait to see you when you get back."It's just about being playful not so serious, this is a set up for a forth date not a divorce, so be cheerful. She responded to your text, now just relax and do exactly what I said. With how I do things you WILL get another date and she WILL begin chasing you 10x more. I'm here to help you. If it helps after you send her this get out the house, go exercise, hang out with a friend, something so you don't continue to think and think and think about this, and when you do think about it, make it positive. Do so by telling yourself she misses you more than you miss her, the next date, and how much fun she's having. Negative thoughts will do nothing but completely blow your chances.
