<human>: I've like this first girl, **E** for 3 years now. Initially she showed a lot of interest and we even had a small date. Then suddenly she started giving me a cold shoulder. When she finally replied to my inquiries about what was going on she said "I need space". She never said why and I can only guess it has something to do with the depression she's been suffering from.

I gave her a year of minimal contact and then messaged her asking if I could re-enter her life. No reply. Another 2 years gone by and next to no contact. Over all this time my heart has done nothing but grow fonder of her. 

This is troublesome for me as I want to move on yet can't. I've tried multiple different things and nothing has worked so far. Now during this time I have also been becoming good friends with another girl, **A**. Initially we started out as a platonic form of relationship but now I'm wondering if I should make a move. The issue is that I don't want to ruin our friendship by making a move and then still being unable to let go of **E**.

Should I make a move with **A** despite the fact I'm not sure entirely of my feelings? Or should I just wait and try other ways to let go of **E**?

Give me the gist of the text in a nutshell
<bot>: in love with a girl who doesn't love me and I want advice as to whether I should try and date another girl when I'm unsure of my feelings towards them
