I'm going to get pics while talking with an ex
Why do you need pics of an ex?
I don't know, I'm not sure about it yet.
That is an impolite thing to do. It's wrong to have ulterior motives when talking to someone. You should be honest with the person about what you are doing.
I'll do what I like and fuck off.
Your relationship is over, it is time to move on. If I were you, I wouldn't bother trying to get petty revenge, your only damaging the relationship even further. Find other hobbies to take up instead of delving in the past.
