This is not recommended as it may lead to something else.
The boy must go and see the girl face to face, talk to her wali and arrange with them everything.

I know non-mahram men & women being in contact before marriage is haram. But would in be haram to interact online if a third party was part of the messages at all times (say, another brother or sister) making sure nothing haram happened? Or would this be khalwa too?

I intend to marry this girl and both of us are going into final year of university. We intend to do the marriage contract now and consummate it when we finish. But in the meantime, she’d stay with her family. So what would be my responsibility as a husband towards her?

When man marry second time without permission of present wife does that mean he ibetrayed his present wife although he has become more responsible towards present wife after second marriage and he left other wife in no men’s land to manage at her own with two kids . So just that reason give him right to be unjust with other wife coz he betrayed to first wife?
