<human>: Summarize the given text in a few sentences.

I was with my boyfriend who I've been dating around 2 months, his ex before me was pretty serious and they had a falling out, he claims to have absolutely no contact with her and to hate her. He was standing across with me messing with his phone and I noticed snapchat was up and her name was at the very top of the list, I think it was the bestfriends list, soo what's the deal with that? Is it possible that it could just be from when they were together? I don't want to unnecessarily bring it up because everything has been going great between us.
<bot>: Saw something strange on my boyfriends phone, is there a possible explanation or does it mean he's lying about having no contact with his ex?
