Dilemma a friend of mine is going through with the one he wants to marry

For context my friend who I’ll call mustafa for now is in a relationship. Not halal by any means but at h to r very least he’s tried his best to avoid any temptation not doing things like zina of course. They are quite perfect together I see how positive his life has changed and how beautiful they seem together. Her family is apparently not the best but in Islam I understand that too hold no bearing over why we should marry someone. So we all think so

Context aside the issue arises recently. His partner seemed to us as if she was purposely adding another man on social media. To us it seems she had added him onto a private story where she would remover her hijab and share gym progress pictures. Granted I’ve seen neither out of respect for my friend but none the less let’s assume it’s true. So now the other guys assume his woman who he does indeed want to marry and has known for the betterment of 2 years is being seen as dangerous, promiscuous and someone who will just ruin his life.

However you may be reading this and thinking that but of course he should just be rid of her after hearing such accusations. However, he came to me privately and asked to confide with me. He talked about how after hearing that he was shaken to the core. He has went home called her and they had discussed. Allegedly according to him she had accidentally added him and then added him to a story because of the fact the man’s display name on the social media app was the same as one of her close friends.

My friend came to me saying he doesn’t know what to do. Albeit I understand it is haram but his intentions are to make it halal. He said that despite this his intentions remain true. He didn’t say explicitly but I could tell he had his own mistakes that kept him humble. I won’t pry into that no one should be made to expose their sins like that.

Anyways he also talked about how the other rumours of her drinking, partying and all these other things are things of the past. He mentioned how she had done these things in the past as a teenager and he had mercy on her so they worked through those issues together. No longer issues anymore but people are now assuming they still are. The one phrase that hurt him the most was when his own friends where saying to him that they couldn’t in good faith watch him walk down an aisle and start a family with someone of this nature. The brother himself is the classic good boy son archetype so perhaps that’s what’s in their minds when they say this.

He’s prayed so much. I see it in his eyes how many tears he’s shed. He doesn’t mind the opinion of others. His only concern is how Allah would view all of this. He tried to be forgiving and merciful like how Allah will be to all of us in sha Allah. Not only to her but to his friends that have bought him these accusations. They’ve made him overthink asking him how much more things she must of done without him knowing and putting negative thoughts into his mind and I can see it affecting him in real time.

He’s told them he’ll sort it out but it’s obvious they want him to berid of her. He asked me if just telling them he got rid of her but still working on these issues and being with her is the right way to go? I love him he’s a very dear friend of mine and I care for him not only in this dunya but the akhira too. His intentions are to make it halal very soon aswell he’s planning to speak to her father soon. So I ask you who are reading this what do I say to him? How do I help him in this time? And is he in the wrong or the right?

One last thing I’d want to mentions. When he talked of forgiving her I mentioned you can’t just forgive blindly. As in yes forgive her (even if she did do all of that) but don’t forget what happened now and what can be done to change it in the future. He’s a soft hearted brother so emotions get to him easily I think it what makes him better than us all. I’d like some answers as to what he should do. Thank you so much god bless you all.

I’m sorry let me clarify her father and mother do know of him and vice versa talks of nikkah are to be happening soon aswell much love.
