If a Muslim friend of mine slept with a woman out of marriage - I would refuse to entertain him, until and unless he does tawbah sincerely.
I will not listen to his relationship problems or offer any advice except - LEAVE HER, SHE IS YOUR HELLFIRE.
I would keep his secret, and not tell anyone.
And I would hope and pray that his secret doesn't become exposed for the world to know and hold against him on the day of judgement.

And some more hadiths on these issue which even the knowledgeable of our times sometimes overlook
Malik :: Book 41 : Hadith 41.1.2
Malik related to me from Yahya ibn Said from Said ibn al-Musayyab that a man from
the Aslam tribe came to Abu Bakr as-Siddiq and said to him, "I have committed adultery." Abu Bakr said to him,
"Have you mentioned this to anyone else?" He said, "No." Abu Bakr said to him, "Then cover it up with the veil of Allah. Allah accepts tawba from his slaves." His self was still unsettled, so he went to Umar ibn al-Khattab. He told him the same as he had said to Abu Bakr, and
Umar told him the same as Abu Bakr had said to him. His self was still not settled so he went to the Messenger of Allah, may Allah bless him and grant him peace, and said to him, "I have committed adultery," insistently. The Messenger of Allah, may Allah bless him and grant him peace,
turned away from him three times. Each time the Messenger of Allah, may Allah bless him and grant him peace, turned away from him
until it became too much. The Messenger of Allah, may Allah bless him and grant him peace, questioned his family, "Does he have an illness which affects his mind,
or is he mad ?" They said, "Messenger of Allah, by Allah, he is well." The Messenger of Allah, may Allah bless him and grant him peace, said, "Unmarried or married?" They said, "Married, Messenger of Allah." The Messenger of Allah, may Allah bless him and grant him peace, gave the order and he was stoned.
next hadith to the above the same incident of

Malik :: Book 41 : Hadith 41.1.3
Malik related to me from Yahya ibn Said that Said ibn al-Musayyab said, "I have heard that the Messenger of Allah, may Allah bless him and grant him peace, said to a man from the Aslam tribe called Hazzal,
'Hazzal, had you veiled him with your cloak, it would have been better for you.' "
Yahya ibn Said said, "I related this hadith in an assembly among whom was Yazid ibn Nuaym ibn Hazzal al-Aslami. Yazid said, 'Hazzal was my grandfather. This hadith is true.' "
