10. If she complains you haven’t texted her lately then it’s a good sign she likes you over text
If she justifies herself when you tease her instead of telling you to F off, then it’s a good sign that she wants you to see her in a better light.
One of my favorite teasing techniques is the infamous push-pull. If you don’t know what it means (how dare you?), it simply says that you sugarcoat your compliment with a negative line to tease her and avoid looking needy/eager.
For example, instead of saying “I like your style,” you can say “I think you got style..despite that weird casquette you wore last time.”
If she defends herself, or tells you, “No, you love my casquette” instead of saying something cold like, “ok,” “Yeah! Cool” Or “f*** off” then she cares about how you see her, which can be a good sign she likes you.
9. She subtly asks you out
This is one of the better signs a girl is flirting through text and that she does actually want to see you.
She’s giving you enough space to bow out if your schedule simply doesn’t allow it, but she’s letting you know that if you’re available, she’s prepared to make time for you.
Be prepared though: while it is perfectly acceptable to not be able to accommodate her this weekend (family in town, work responsibilities, etc.), the onus is now on you to reschedule.
She 
thinks you’re being distant and wants more time with you, so she complains instead of telling you bluntly, “Hey, I want attention.”
Here for instance. In addition to quadruple-texting me in less than a minute, she’s complaining that I’m not giving her time.
Also, when you tell a girl I hate you and she replies with something like “no you don’t” in a fun way, then it’s probably how she wants you to feel about her. This is, again, an excellent sign she likes you over text.
11. She asks personal questions
If you get that a lot, then it’s a very good sign she likes you over text. She’s literally saying “you’re mysterious to me. It’s exciting, and I wanna know more.”
What you should do, however, is don’t spill all the beans because once you throw everything out in public, you become common and predictable, just like every other guy out there.
Don’t reveal everything about you early on. Just a little here and a little there and keep it this way. Don’t be like a comedian on a talent show who gives their best game in the first call-up, then suck miserably in the second.
12. She remembers the things you say
Some people have good memories, but a girl won’t bother remembering details about you unless she kinda cares. So if she tells you how much she liked the blueberry cake at Starbucks (that you recommended), or better, brings you one the next time she sees you then she got out of her way to show that she likes you.
13. She copies your slang
You know you’re spending a good time with someone when your vocabulary rubs on theirs. It’s just how chemistry works.
If the girl you’re texting starts using your favorite slang/terms then it’s a subtle sign she’s trying to identify with your lingo and get closer to you….aka, she probably likes you.
For instance, I don’t use many emojis when I’m talking to a girl early on. I use (:p or :D) instead which reflects my emotions without making me look super eager (I highly recommend doing this).
