Well I loved her all the time , we were very good friends but she always used to say she doesn't want a boyfriend and she doesn't believe in love ! But one day I asked her out while she was online and she said said NO to me , after that day she is ignoring me continuously .
I sent her messeges and she said " Dont worry its ok " but later on again she didn't reply any of my messeges ,
I love her so much just want to be friends with her again we were high school friends , she comes online mostly and has not blocked me but doenst talk to me either... what do I do to become her friend again ?

Stop hounding her, stop sending messages, just let it be.

If she wants to keep your friendship she'll come to you. If you keep pestering she may just decide you're more work then you're worth.

I'm sorry to hear about your situation.

She's actually doing you a favor. If she responded to your messages, it will give you false hope.

Maybe one day you guys can be friends, but you will have to get over her first. So for now, focus on getting over her and moving on with your life.

If she wanted a friendship, she will come find you. You can't force a friendship with someone who doesn't want it.
