I used to have her Facebook password and she was fine with it earlier , since she has started talking to a new guy on faacebook she was changed her password and said that she dusnt like me logging into her account anymore... She twists all answers to the questions I ask her n we now generally end up in a fight... Now she isn't returning to my calls and says ill get back to you when I feel like n that she loves me... This is a regular thing and I don't know what to do... She ends up not talking for days without giving a reason... Help me on what I should do...

It is a bit too much to have each other's passwords, unless you're extremely serious with each other.

That being said, it sounds like you're drifting apart. If you can't find ways to repair or work out your problems, then it might be time to walk away from this relationship.

We are drifting apart not frm the relationship bt frm each other... we would marry anyway I js want this to be good nt a burden...

Knowing what you want is the first step. Does she know what you want? She needs to know where you stand. Once she knows, then she can take her timeto figure out what she wants.

Sounds like she's not even sure what she wants, so give her some time to figure it out.
