She use to study with me when I was in six standard and after 12 yrs we met on Facebook and started chatting as a friend for 2 months and we were in a relationship, but I still haven't seen her. We use to chat in phone and Facebook. She saw my old Facebook message which I did not tell her before because I was scared of losing her. Now she is not receiving my call. Her phone is switch off since 1 week. I love her so much I want to marry her I don't want to lose her she also loves me.

Let go, she's not missing your calls by accident. Stop talking to her, and trrying to reach her and move on. You can't tell if you want to marry someone 2 months into the relationship sorry.

Someone who loves you doesn't stop receiving your calls my friend. You met online, she dumped you on line, because she changed her mind about you for whatever reason.

Time to let go, heal, and make new memories, friends, and carry on with your life. Maybe a real girl, real dates, real fun.

Maybe she has lost her phone or something of the sort. Regardless, to be on the safe side, start moving on, assume that she is ignoring you because she is not interested. Stop trying to contact her, if she wants to talk, she can make the move to talk to you.
