As looking/meeting stranger females is haram and one cannot go for relation with any unmarried. If one's parents are not serious about child's marriage. How can one search and come close to a suitable partner.
In some societies parents arrange for their children' marriage. Or one finds a match in relatives. If one is not lucky this way how will he get married.
Those who don't abide by Islam easily get done with these issues. Should one wait for God's blessing or one has to break lines.
Whether on social media or real world it is almost impossible to be good and follow Islam and find a good partner as this way you will be decent but unless you take step no one will make you offer. If you lose the bound of Islam thing seem apparently easy in going and exploring fortune; but that way also stalking around is not what everyone will wish to do.
And yet another issue if you go openly with this intention of meeting you can't justify this stalking behavior in Islam and no good person will accept such offers, and on other hand staying away and decently waiting with 'sabar' apparently never seems ending in success.
As answer I am expecting Islamic guideline for searching partner at one's own. Keeping oneself away from sin and taking all features in mind like comfort and mutual understanding.
