<human>: Could you distill the essence of the text into 1-3 sentences?

Okay, I might as well start this off saying we have been best friends since we were both about 12-13 years old and were going out from the time I was 15 until just the end of march (my birthday being just a week later, we at that point have been going out for ~1.5 years). We had to break up because my parents seriously didnt approve of me dating her, and we tried to keep in touch secretly a few times but it all fell apart then.

Since then I had 2 other girlfriends (both were very short term) and she just found someone else maybe about a month ago, and I am super jealous of this fact. Part of me feels like I am still in love wih her but the thought of dating her again makes me terrified (we were very on and off because of my parents questioning and her bailing when I needed her).

We are still friends and sometimes talk in secret and I have already told her I still had feelings for her, to which she told me she just doesnt feel the same any more. I just don't know how to get over this jealous feeling and I certainly don't want to end our friendship. It just bugs me.
<bot>: I am jealous of the fact that a girl who i had an on and off relationship has someone else while I still sort of have feelings for her, and I can't hold a relationship of my own anymore.
