The technical confusion about a break-up.

So with the current issue, I have this confusion in my head about how to act and what to do after a break-up.

1. If you happen to share an account of cinema membership, do you change the details or your ex does it? How about the remaining balance in that card? Who claims it? Do you refund the money?

2. Do you wait for your ex to change the Facebook status first from being in a relationship to become single? Or you initiate the change?

3. What do you say to people who adore your lovestory and ask you why you broke up? Do you frame your ex into a bad figure or you just admit that it's your fault? Or ignore?

4. If you miss your ex, like for example the way they say hi or just checking out how you're doing, should you ask your ex first without considering that's going to contradict the fact that a break up means no more strings attached? If you finally decide to do it, how to make it not look like you're desperate of wanting to be together again?

5. Let's say your ex doesn't tell many people around them that you have broken up. Suddenly a friend of your ex said hi and invited you to come to a party. Would you be the one who tells them that you are no longer in a relationship with their friend?

6. With the same context in no.5, what if your ex's parents (who you know like you) text you and ask how you doing and invite you to an event? Do you consult your ex first asking what to say?

7. Your close friends know your side story, they're trying to fix you up with someone new. Would you dumbly refuse and say you want to be single for a while because you still aren't over your ex yet? Or you're actually keen to meet new people for the sake of refreshment and consolidation?

8. As a social media user, there are a few times you are tempted to post what you're feeling. How to express that you miss the memories you've had (not the person) without making an impression that you are desperate and really broken about the relationship itself? Or are yiu just shutting down and being silent at all?

9. There's one time your ex texted you saying hi and just chatting about stuff. Do you respond cold no matter how bad you actually want the same thing? Or you just act sweet and go cheesy all the way to try to win your ex's heart back?

10. How to stop doing small habits that you are comfortable with when you were still together with your ex? For example, telling funny things happened in your office, or funny pictures in 9gag, or just simply a new movie trailer you two have been wanting to watch?
