Realised i was the rebound, is that it now?

So i started talking to an old friend last year who ive known from school (she used to like me when we were younger) and she instantly developed deep feelings for me (we are both 22) i told her i woudnt take us further unless she leaves her cheating boyfriend which she did, and we rapidly hit it off.. i always knew she had a thing for me and is incredibly attracted to me.. she was alot more attached than i was and her family always said to her that hes too good for you blabla but i never thought much of it.. i was a little naive and didnt really think about if it was a rebound or not. She never brought up her ex and i do believe she is over him.. she started saying i love you very early and even said shes gonna marry me and have my kids. It kind of felt a bit surreal but i always kept a bit of a distance because subconsiously i felt that it was a little too surreal.

She wanted me to go on holidays with her family which i refused as i thought it was too early l, i spent alot of time with her family and everything seemed to go a little fast but i wasnt complaining as i thought she just really loved me and part of me genuinly believes that.

After 11 months when she started going to uni and got busier with work i felt a bit of distance from her.. she was in a bad place when i met her and i feel like i got her confidence up as shes very insecure and doesnt really think highly of herself i always treated her well even though i didnt fully open up and kept a bit of distance like i said.

She called me up one day and just ended it out of nowhere and i was devasted, i gave her a week and told her i needed to speak to her and get some closure.. i tried to convince her back but she seemed so cold and over me and just wasnt having it, we ended up sleeping together one last time and after that she started crying and saying how i was the best thing ever and that she still needs to hear my voice and please dont make it obvious that youre seeing someone so she went home and i began NC

Its been about 5 weeks and im in a better place than i was a month ago, shes tried to message me 3-4 times to see how im doing and to compliment me on my new hairstyle but ive ignored them.. my gut tells me she will want me back in the future but im not counting on it i dont know if i could accept her back..

Just felt like i wanted a bit of advise. Thanks x
