<human>: So, I was over at my girlfriends house the other day and grabbed her iPad and started flipping through it, saw some texts that kinda got my attention. Here is a transcript:

- Nov 7th, He sends her a picture with a million candy crush invites      and asks "really?"

- She doesn't respond

- Nov 10th after a sort of fight we had read like this

Her "I'm drunk"

Him "and no invite? How rude"

Her "Invite"

Him "doesn't count going to sleep text tomorrow"

Her, asks a random question 

Next Day Him, answers question

Nov 12th Him, "Hey, haven't heard back from you for a while too cool for me now, lol"

She doesn't respond

Nov 15th:
Him, "too cool for me now?"

Her basically that she is in a relationship and happy and doesn't want to ruin it

Him, stuff about how he was surprised about her texting and impressed that she thought of him

her, chit chat about what he is up to etc...

Obviously deleted messages in between here

December 17 (we went out downtown with a few friends)

Him "sorry I can't come out tonight"

Her "it's gonna be a blasty blast"

Dec 18

Him "how was last night"

Unknown messages here

Later Dec 18

him "lol hope you feel not hungover soon"

End of known messages.

After seeing this I panicked and when she wasn't near it I checked her phone and all of the messages are deleted. 

I don't know what to say or if I need to say anything, I haven't suspected that she was cheating and she even said she didn't want to ruin our relationship... I just don't know if I should say anything or how I should say it if I do.

Can you provide a brief overview of the text?
<bot>: Girlfriend drunk texted a ex hook-up and told him about us but I'm just not sure if there is something going on.
