All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
It is forbidden to continue talking with each other as long as there is no need. Because continuing to talk for no need may lead to making an appointment to meet, talking face to face, and exchanging glances; and this is forbidden. Such a situation may also lead to committing Zina (fornication and/or adultery); we seek refuge in Allah from this.
Thus, we advise you stop such a relationship until Allah Almighty, makes it easy for you to marry.
We ask Allah to help all of us to follow His Orders and the Sunnah of His Messenger .

Allah knows best.
