Greetings to the great minds in @steemfamily Community whom I believe also are lovers of the Family.
Family life comprises of the father, mother and Children with in-laws inclusive in the extended aspect of it.
It's my pleasure to drop my view as comment on this subject matter cohabitation between Adults, children and parents.
I want to begin by saying that there is time for everything under the sun, a time to be born , a time to grow, a time to live with your parents, w time to grow up into a full grown adult , a time to leave your parents and live on your own. Having said this therefore , I will opine that there is no point still living under the same roof with your parents once you are grown up and approaching the age of marriage. Once you have started contemplating Marriage or nursing the idea of marriage it will be adviseable and to your own best interest to strive to rent a house and stay on your own for Marita convenience. You need not marry and become a liability to your parents. Also you need not marry and allow your parent to meddle or interfere in your matrimonial issue. The Holy Scripture says.

For This reason(i.e. for the sake of Marriage) shall a man LEAVE his father and mother and CLEAVE to his wife and then the two shall become one flesh

So for you to become one flesh with your partner you must first LEAVE in order to CLEAVE.
85% OF people who cohabitate with their parents after marriage always have their marriages mesmerized.
Thanks I am @linheart. A newly married mother of two . I am just clocking 4 years in the marriage journey. Both me and my hubby are not living with our parents and we don't ever to do so. However that does not barr our parents from visiting us to spend some good number of time with us whenever they so wish
Thanks once more @dternfamily
