then y do people complain soooooooooooo much that shaadi ye hai,wo hai,v r fed up,offended,bla bla...
well everything has its ups and downs...I mean in a marriage u are sharing ur room...so imagine...u both need space..u both need to have your own private time as well...people do get frustrated because you have to become one with your partner and that always isn't the case...there will be days where u will argue, fight..but at the end of the day you'll still have someone who loves, cares for you and will always be there for you.
Imagine living in the same room with ur sister for 5+ years..you guys are bound to fight. Forget sister..imagine sharing an apartment with your best friend...I've heard so many girls..guys even fight with their roommates over silly stuff.
heck my and my sister share a bathroom...she always has to use it when I need to go...that gets me pissed and we end up fighting over the bathroom.
You know what else...people tend to complain a lot more than appreciate. Sadly women complain too much over the smallest things. I've heard my mom complain about my dad..and my dad to me is the perfect husband.
Don't let people scare you..I too am afraid of marriage..but you just have to make dua and trust Allah (SWT).
Rather than listening to complaints, ask those same people how they manage to keep their marraige going, how they resolve their complaints/issues. That just might help you be less afraid of marriage.
