Hmmmmm:hmm: so whats the problem?? Welcome to marriage bro
Part of the problem is that you both went into this thinking you were more mature than you are (about relationships). These problems are to be expected. It's not always fun and roses.
You need to get your own place. You and your wife need your space. You need to grow in a relaionship together, that is made difficult with having a house full of family, especially since you have only been married one year.
Don't let the stess of all these things pull you 2 apart. Lower your standards just a little when it comes to your living condition, you are just starting a new life together.

You have plenty of time to worry about buying the Taj Mahal for her;D
At least this would let you start your marriage of right by being married to your wife......not the whole family
I know noone whants to listen to the token Christian dude here, but....I am married....and men are men......and women are women.
One more piece of advice, she is your wife now, don't ignore her feelings towards your family. And make sure to communicate, don't just keep your mouth shut, I used to be that way and it makes things worseimsad.
God give you and your wife peace and blessings, God may their marriage be long and prosperous. Ameen.
