Eh! Bad topic. First deal with maturity. Hope that would inevitably land into something to do with relationships (keeping in mind my overworked grey cells) ;-~
Hope we all agree that maturity is something 
elusive that comes with age, education, exposure to different cultures, interaction with multiple communities and has nothing do with CMM (Capability Maturity Model) practices led down by Carnegie Mellon University for improving the maturity of any process(industrial, techno-commercial). Wish they had a model for improving maturity of a person or 
a relationship for that matter.
Univ of Wisconsin tells that "When a person can live with her past without being bogged down by it, she remains adaptable, capable of continued change, then she is mature."
The mature individual can accept her own shortcomings, realise her faults and is usually much mellowed about life. The mature person knows that she has to go on choosing alternatives, that each alternative costs something, and there are things she will never be able to do and experience, but then 
maturity is about giving up a lot and realizing how much to give up. She also knows that there are things she will never be able to do again, that she can never recapture the youth or relive her 
first encounters with certain experiences. She will give up all temptations for a cause that has long time effect. She knows that her integrity would be continually threatened by 
practical demands, by seductive temptations, by concessions, by conflicting values, and can only be preserved at the cost strong resolve, 
love for life and faith in mankind. A matured person would take that extra step (often interpreted by immatures as sacrifice or compromise) to make things happen, to keep falling pieces together, to 
caress a lonely heart. She would make that effort to survive a relationship that is going through a bad patch or may not have blossomed completely.
I don't see too many trendy and smart youth 
(both guys and gals) doing such things for their relationships; they are all about move-ons, break-ups, divorces. They are afraid to take that risk as it challenges their 
ego, dreams, sense of freedom and pride. They are all about take-it- easy.Definitely they are good, attractive, smart people who have a lot going for themselves but they are just afraid to settle. So most beautiful men and women have the most confused and most hazy souls. They think settling down will make them like the other 'schmucks'.
Believe me. Trust me. Having one to relate to, talk to, share your life is something so sublime and special; it makes life so easy to live and enjoy. 
Extend your hand for the person waiting. Your relationship deserves your maturity not whims. Amen!
