Relationships are all about good communication from both sides(talking and listening),my relationship in its early days would have had its problems because back then it was early days,the honeymoon period if want to call it that and them communication skills take time to work on and build upon.As time went on we both realise that we want the same things in life and that its easier to work things out when some adult communication is present.
Shell talk when she's ready man and not before it.
