Assalamu Alaikum wa rahmatullahi wa Barakatuh

Thank you for your question.
Allah Most High says, “Do not marry unbelieving
women until they believe [...] And do not marry
(your women) to unbelievers until they
believe.” [Qur'an 2:221]

It is clear that Allah has not made it permissible for
Muslims to marry non-Muslims, though there is an
exception for Muslim men to marry women from
the People of the Book (i.e. Jews and Christians).

Hanafi scholars have pointed out that even this
exception is in many cases disliked or even sinful if
one cannot be sure that it will not influence one’s
religious devotion or beliefs, or that of one’s
children.
Among the many wisdoms of this ruling is the
preservation of the religion of Islam and prevention
of harm to one’s religious foundation. This ruling is
an insight into the importance of the sacred trust
one undertakes by marrying, having children, and
raising them to be obedient God-conscious
servants.
In terms of consequence, one’s marriage would not
be valid if they married one other than whom Allah
has permitted for them, and therefore the man and
woman would be considered to be living outside of
wedlock.

Muslims should guard their personal interactions
according to the teachings of Islam. If a Muslim
gets himself or herself in a situation where they
desperately want to marry one with whom marriage
is not permissible, they should immediately pull
away and speak to a scholar.

The scholar should be able to evaluate the
situation and determine which of the two options is
more suitable:

(1) proposing the idea to the non-
Muslim to study Islam and adopt the faith so that
there can be a valid marriage or

(2) asking the
couple to leave the relationship altogether.
It will no doubt take one time to heal if strong
feelings had developed, but no one leaves
something for the sake of Allah except that He
rewards them and replaces their loss with
something better for them.

Allah Most High says,
“And those who strive for Us - We will surely guide
them to Our ways. And indeed, Allah is with the
doers of good.” [Qur'an 29:69]

And Allah knows best.
