Lost my love life

I am a girl who fell in love with another girl for the first time,I love her so much & never felt this way toward anyone before, I love everything about her, we became so close, we both make each other happy, happiness that I've never experienced before, but two weeks ago after making love she knew that am not thinking to spend my whole life with a girl..I ruined everything, although that day she put an engagement ring in my finger while we kissing which means she's was serious about our relation. After that day I realized that I do wanna spend my life with a girl & specificly with her, I tried to fix the mistake I did and told her that I do wanna spend my whole life with her & I'm ready to do anything to get her back..but she's deppresed & she don't think it's good to get back to each other..& things got worse because a close person to her died, so it's harder now to try to get her back..I don't know what should I do,I can't let her go, I'm crying everynight, we were so good together everything was just great.. if i don't talk to her she doesnt talk to me, I'm afraid that she has no more feelings for me & that she's over me now I love her & I want her back

speak to her once tell her how u feel and see what she wants
