They can but not without a lot of work and probably counseling.<br />
They'd probably be more comforted in finding a kindred spirit but on the other hand, if neither of them is stable, then they can't really be the example or "rock" for the other. It's like trying to prevent a tornado from tearing everything up by putting another tornado in its path - just creates more destruction.
my wife and I have been together 6 years and getting stronger all the time. evidence to the affirmative
Anything is possible with love. I say yes.
If they are both real to each other, than Yes they can. I know couples that started out that way. They took it slow. Started out as just friends. Let that friendship grow. People said they would Never Last but this year is their 32nd year together and they have been Married for 28 years they are happier than ever and love each other as much as to people can. By the way most of the people who said they would last back then are Divorced and re- married now. I keep talking to them. Telling them to go slow. To this day we are the best of Friends. So yes if they become friends then lovers .
Yes if you lock yourselves in a box
Yes, if they agree that somethings do not matter that much to them.
I seen this happen, the children bully them because they can.
