How is this love story. what do you think, please be frank, open your mind and give me feedbacks.?

well, we met, became frnds (best frnds). She said she is single... We r together from 6 months. I have proposed her b4 3 months. She declined. I am not giving up cause i truly love her. She behaves very normal with me. Though i found a bit change in her behavior after i proposed her. We used to hang out, but now she says no many times i ask her out. But we meet. Everytime i say i love you, she says i love you as a frnd only. I don't get it. I mean i understand but don't want to hear that. I don't want to understand that.

one day she said, she had a bf, which is x now and she still loves him. They r in contact and therefore we cannot be a couple. I cried for a week or more. Bt m ok now and doing what i used to do, loving her. (not any physical contact). I give her gifts and do things for her which make her happy. And pls don't even think that she is selfish. Cause she does not expect anything from me. And i have took a forced promise to accept my gifts. I love her soul, i know you guys will say, i am mad. But yes i am. I will keep loving her till i die. It doesn't matter she loves me or not or what. This is my story, long story in short.

pls no bad comments, you'll know this feeling if you have ever loved someone.
