First of all you need to clearly understand that marriage is not an easy task and anyone going into marriage should be well prepared before going into it

When i talk about being prepared i mean that the man should be financially,emotionally,morally,spiritually and intelligently prepared because these are the things that can enable him to overcome the challenges in the marriage,concerning your question i think it depends on the culture and tradtion of the country where you are from,in some african countries it is not proper to marry your wife and still be living in your parents house..

Personally i do not see anything wrong in getting married and still continue to live with your parents,i see no big deal in it but also i have to respect the cultures or traditions of other people,so if your tradition forbids it then it means it is not proper but if your tradition allows it then is its a proper decision that can be taken
