is my ex reconsidering?

me and my ex broke up about 5 to 6 months ago and he's with another girl. but out of the blue he starts to Snapchat me and we talked all day. he even told me he was lonely and bored. is he hinting at something? he's usually with his new girlfriend all the time. he was even telling me what he was doing. is my ex reconsidering our breakup? someone help me!
