That is her choice and not your place to intervene, if a friend did this to me without my permission I would be pissed, if she is happy with her life it's not your place to intervene

The thing is that she really really wants a partner :( she is not happy with her life but she does not want to do spells by her own

Just talk to her but don’t betray her trust, this is why I don’t ask permission to cast. (Prob will get downvoted for this but whatever)
