There's an anecdote related to Shaykh Wahid Khurasani (ha) that comes to the mind. A lady once complained to him that she has been praying to get married for some time, but her prayers are not being answered. She's advancing in age, her brothers tease her, what should she do? The Shaykh contemplated for some time and replied that the wish has been granted, but Allah (سُبْحَانَهُ وَ تَعَالَى) is delaying its fulfilment till the opportune moment appears.
It so happens that sometimes that our wish may be granted by Allah (سُبْحَانَهُ وَ تَعَالَى), but He may delay its actualization till the time is right for us. For instance, He may well have picked a suitable husband for you, but He's delaying your marriage until the husband is financially stable, or he's finished with his studies, or emotionally mature enough to commit to you for life.
The qadar of Allah (سُبْحَانَهُ وَ تَعَالَى) is unfathomable. Have patience. Don't be rushed by peer pressure.
