Review your intention of getting married
Marriage is recommended for partners who share a common way of life. The matrimonial partners should be able to fulfil their purpose of creation as defined by Allah. They should be able to effectively carry out their responsibility as care-takers (khalifah) of earth. They should share the common goal of building a well integrated Muslim community and be able to work harmoniously towards it.
Following factors should be considered when seeking a Muslim spouse for brothers and sisters.
Be clear about your expectations about your future spouse
Marriage is part of faith and it is part of the Sunnah of the Prophet Muhammad (peace and blessings be upon him). It is a commitment and relationship that should start with good faith and good intention in your heart.
If you're looking for a spouse don't stare or make other person uncomfortable
Abu Hurairah related that the Prophet said: “Men choose women for four reasons: for their money, for their rank, for their beauty and for their religion, but marry one who is religious and you will succeed” (Bukhari, Muslim).
This of course, applies to women as well.
Prophet Muhammad (S) assured the bounty of Allah to those who wish to get married and live a pure and clean life. "Three groups of people Allah obliged Himself to help them: Mujahid in the cause of Allah, a worker to pay his debt, and the one who wants to marry to live a chaste life". (Tirmidhi)
When you meet, don't be alone
It is narrated that Prphet Muhammad (peace be upon him) said that “When one of you asked a woman in marriage, if he is able to look at what will induce him to marry her, he should do so. ...” (Abu Dawud).
However also consider the following quotes from the Quran:
“Tell the believing men to lower their gaze and be modest. That is purer for them. Lo! Allah is aware of what they do” (Quran 24:30).
“And tell the believing women to lower their gaze and be modest, and to display of their adornment only that which is apparent, and to draw their veils over their bosoms...” (Quran 24:31).
The Prophet said: “Whenever a man is alone with a woman the Shaytan makes a third” (Tirmidhi).
He also advised men: “Not one of you should meet a woman alone unless she is accompanied by a relative within the prohibited degrees” (Bukhari, Muslim).
The purpose of meeting and talking to each other must also remain within Islamic guidelines. The conversations between potential mates cannot be talking just for the sake of talking. There should be a firm and clear intention of either pursuing engagement and marriage, or, if one of the two or both the man and woman feel they are not compatible, a quick end to the relationship.
This ensures both sides are safe from getting hurt more than they could in this kind of a situation and remain within the bounds of Islam, Insha Allah.
