#8: Be Your True Self
The simplest of relationship rules is to remain the person that the other half fell in love with. When people change after a commitment, they raise suspicion and it can be very worrisome for the other partner. While it’s a good thing to change for the better, it’s always best to try and remain the same person you once were. Your partner fell in love with the person you once were and probably expects you to stay the same, so there’s no reason to ever change yourself.
