Is my ex in a rebound?

My ex girlfriend broke up with me 9 weeks ago, after a 3 month relationship but we have been friends for over a year. after 3 weeks of trying to get her back i started no contact for 30 days. now after the break up she still texted me on her own free will even during the 30 days of no contact i just replied to these texts in a positve way, she also did things to make me jealous hinting at a new man. anyway i called her for the first time on my own about a week ago and just said i had somthing i bought that she might like would she want to come get it and she said yes. but during the conversation she said she was sleeping on my side of town on a certain day so she would pick it up then. it didnt make sense at the time but then when the day came for her to get it she called when i picked up nobody said anything , i called back left a message , she texted back that her bf rolled over and her phone dialed my number and she was sorry. my question is this a rebound relationship and is she still into me or should i just give up?
