Capricorns are though shells to crack but inside they are just filled with melted chocolate hearts that will heat up to almost anything. They hate being vulnerable and will only open up to you if they feel some sort of connection. Which in itself is a huge step for a cappy.
There is no real way to speed up the process. Only time will cause the Cappy to "warm up to you". Pressure will just cause her to close up on you and push you out. They don't like to feel like they owe you something or have to act impulsively. With that being said they will think about their every gesture almost a hundred times before giving out any signals.
I often think this is why the capricorn is mistaken for cold when in reality they are just contemplating their next move. So cut her some slack, she only strives for perfection. ;)
Yes, the capricorn will think out scenarios before they happen and she's most likely the first one to plan her outfits, even if she won't admit it. - so how about a compliment for all her efforts? -
With all being said, don't mistake the Capricorn's soft side for lack of confidence or being weak. She will always remain strong till the end. Capricorns have an ability to pick themselves up quite quickly and will always protect themselves by building walls or cutting you out. BUT she does care, and when she cares - she won't stop caring.
