I strongly reject bf/gf relationship, if your baat is pakki and you and your significant had spoken one or two time before rishta pakka, then you dont need to discuss feeling, likes, and future planning.
obviously any physical relation even if it was minor like hugging, kissing (including french kiss) isnt appropriate, you will lost your innocence before marriage, and your face will no longer show NOOR (a bless light on face from Allah), and most important is that all these kind of relationship are neither rewarded by Allah without Nikkah.
