<human>: Can you provide a brief rundown of the text in within 3 sentences?

First, apologies for the novelty account. 

Second: Backstory.

Last year, i [20, M] met a girl at my university. Lets call her X [19, F], for simplicty's sake. It took us a while to start talking properly, but we managed to hit off a very solid friendship. We became very close, and about 6 months after meeting, i gathered enough courage to ask her out. She rejected me, on very fair reasoning. I wasn't bitter, things didn't become awkward.

Shortly after that, i decided to abandon the uni ship (for completely unrelated reasons). When it was coming closer to the end of year, i managed to catch wind that one of her friends (lets call her Y) was interested in getting to know me better. 

Pretty much two days before leaving,  X finally came out saying that she did have feelings for me and was wrong bouncing me off beforehand. I shrugged it off, and said "let me find out where my life is going before we decide anything".

Over the summer, i managed to stabilise, and me and X started dating. I also started talking to Y, because she seemed like the person i would find interesting (in a non-relationship sense). 

X managed to catch wind of me talking with Y, and just asked me to be sensible, but was not against it.

Enough backstory, that's about it.

My question is: Am i just being paranoid thinking that if Y showed no interested, X might have not said how she felt? Or is this something worth bringing up?

Thanks in advance, and apologies if i don't respond to anything promptly, it's getting late where i am and i need some sleep.
<bot>: I suspect girlfriend only said how she felt (before we were dating) because another of her friends said she was interested in me. Am i being paranoid?
