My ex called me by accident?

i got a phone call from my ex girlfriend and when I picked up I heard background noise and heard her say "omg who did you call?" and got on the phone and said "hey I'm sorry my little cousin got into my phone and accidentally dialed you" is that believable or do you think she did it on purpose. I mean we broke up and ill admit I broke her heart and never spoke to her again, even though I knew she wanted to stay friends? we had some very intimate moments and I was her first time for everything..but yeah... is this her way of trying to remind me of her?
