no man is an island.
We were nvr meant to be alone. Singlehood is enjoyable but eventually you'll long for company.
Pple in a r/s may seem to have it tough is only because they are not with the right partner or not having their issues ironed out.
In a beautiful and committed r/s.. 1 + 1 = 11!

One may walk the path of being uncommitted, but eventually most will want to settle down. Imagine at 50.. u want someone to love u for who u are, u want kids to take care of u n keep u company.
We are only young for few yrs but old for decades... Can you truly say you want to be single for life?
