Praise be to Allaah.
If the matter is as you describe in your question, we advise
you to strive hard to distance yourself from this man and to cut off this
relationship that is based on great love for him, because that is damaging
to your religious commitment, and the affect of that is clear from your
words about your deep attachment to him, your lengthy relationship with him
and your not being able to leave him. All of that is very damaging to the
Muslim’s ‘aqeedah (belief) which requires him to disavow the disbelievers
and to take as close friends and love the believers. Allah, may He be
exalted, says (interpretation of the meaning):
“You (O Muhammad SAW) will not find any people who believe
in Allah and the Last Day, making friendship with those who oppose Allah and
His Messenger (Muhammad SAW ), even though they were their fathers, or their
sons, or their brothers, or their kindred (people). For such He has written
Faith in their hearts, and strengthened them with Rooh (proofs, light and
true guidance) from Himself. And We will admit them to Gardens (Paradise)
under which rivers flow, to dwell therein (forever). Allah is pleased with
them, and they with Him. They are the Party of Allah. Verily, it is the
Party of Allah that will be the successful.”
[al-Mujaadilah 58:22].
This love of the heart is a serious matter, because it is
contrary to the teachings of al-wala’ wa’l-bara’ (love and loyalty versus
disavowal and enmity), which is one of the most important basic principles
of Islam and one of the strongest bonds of faith, which is indicated by a
great deal of evidence from the Qur’an and Sunnah. Please see the answer to
question no. 47322 and

This does not mean that you cannot treat him kindly if you
meet him or you have a class together or work together, without being eager
to meet him outside of school or work. So strive to correct yourself and end
this forbidden friendship. If it so happens that you meet for any reason,
make it your main concern to make him love Islam and call him to it, and
warn him of the grave situation that he is in, in the hope that Allah may
decree that he be guided out your hand. At that time, your love for him will
be beneficial to him when you to call him to Islam. We ask Allah to help you
to do that which is good.
And Allah knows best.
