Blessed be the humble. They will succeed where others will not.
You have a generous soul with much love to give. And your insightful nature enables you to see through the exterior of another.
This other individual, for whom you have strong and growing feelings, may seem stern, cold, perhaps uninterested. This situation may prevail for some time. It will take time, and tenacity on your part to break through their tough shell.
But you will persevere. You will not allow yourself to be deterred by the insecurity of an individual who lives unaware of the deep emotions inside. Your affectionate persistence will win in the end.
