<human>: I was seeing a girl i really like for a about 3 years now. Things were great but i wasnt really looking to be in a serious relationship so i didnt really let it develop into one on my end. She fell in love with me and kept wanting to be together. Recently things became distant and i found out she no longer feels the same and had met someone. Around that time i realize wtf i missed out on and that i had fallen in love with this girl and now its too late to change anything. I told her how i feel and that i want another chance to actually make it work now. Didnt do anything to change the situation. Then literally a about 2-3 months later find out they have already moved in together. 

So some opinions would be appreacited. Why is her new relationship moving so quickly and is there any actual chance that that relationship might not work out and we get another chance being that it seems to be moving so fast currently.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Took too long to tell someone i love them and want to be together. Now wondering if i can get them back.
