I got a proposal from a man I spoke to online 3 yrs ago. He was a new revert then, I encouraged him to tawhid. I regret that I spoke casually.He recently contacted me said he never forgot me, now wants to marry me, meet parents. Is his approach appropriate,should I speak to him formally? He’s salafi

Ustadh AbdulAziz al-Haqqan

The correct way is for him to go to your wali and propose through him. After that, speaking to him about the marriage is allowed with your mahram present and without khalwa, and what came before does not affect the marriage if you both repented sincerely.
