Its difficult to gain traction and build rapport with girls that give you inches where miles are required. I personally encountered a woman like that 3months ago, and will share with you my learning from the experience.
Here is the thing:
Some girls (even the beautiful ones) lack the social skillset that most of us consider basic. For them communication with strangers triggers anxiety, and is a pursuit that they would avoid all together if they didnt need the deek (from men) or the income (from employers). These girls are socio-phobes and only interact with men because their hormones push them and give them no other choice. Some are in this state because they are damaged goods and carry deep cracks from their pasts (sex abuse, physical abuse, abandonment, lack of love etc etc). This brokenness manifests itself in these short texts you are referring to.
There are 2 paths for you to choose from.
Either you exercise patience and endure the frustrating interaction for weeks or months, until they feel comfortable enough to open up more to you and reveal the root cause of their inner cracks. This demands a huge investment of emotional energy from you, since it takes big doses of discipline and patience for a rabbit to travel at a pace a tortoise finds comfortable. a form of adult babysitting. Ask yourself if the huge input from you justifies the end rewards.
Or you cut them loose and conserve your energy for more enjoyable interactions with girls that have the social skills and appetite to engage you in ways that stimulate you. You want to see a message notification from a girl and rub your hands in anticipation of what you are about to read.
In conclusion:
Broken girls need love too and are in that unfortunate state usually because they are victims of an unsavoury past. They want to enjoy companionship and intimacy like everyone else out there, but are stunted by the private burdens they carry.
Its honourable community service to give them a chance and walk with them at a pace they can manage. Most of them make loyal girlfriends and wives, because they latch on and dig their talons into you once you get their fire going, because they know they dont have what it takes to dip in and out of the dating pool at will. However, there is a trade-off with them. Once you choose to take them on, be prepared to absorb the personality issues they come with. Eating disorders, addictions, suicidal ideation, possessiveness, passive aggression, bitterness, negative mindedness, anxiety, unannounced meltdowns etc are common with them.
I hope this is helpful
