Possibly.
Playing hard to get.
If she agreed to go on a date with you, then she probaley likes you. Even if she dosnt respond to your texts. Maybe she lost or phone or her battery died... She might be really nervous to talk to you. Their is many reasonable answers.
no, she probably wants you to do it first cuz you're the guy
He likes you.
it means she likes u
It is very likely that if a guy responds to your texts when he is busy, he likes you.
she likes you, dude. xx stands for "kisses" like the phrase "XO" hugs and kisses.
It means he likes her back.
Depends on what those " couple word answers " are. It doesn't mean bad or good. This may be the way she communicates. She may talk to a lot of people so texts might be her way of getting to people in a timely manner. If you are a expressive person this may unnerve you but realize real conversations are said over the phone but truly face to face. Use texts as a way to catch up quickly not for heartfelt emotional conversations. Good luck.
yea he likes you more than anyone else
It could mean that he likes the girl that likes him. :)
