You have every right to be friends and hang out with whomever you choose... just like she does...
I understand that you want to "fix" the day and smooth it over...
The only BIG question here is, Why do you want to integrate into the "poker boys" group? And whatever your answer... just check it against any underlying, unconscious hope that you can keep tabs on your W through these people, or that you can manipulate your W through them...
If she would really D you because of the friends you choose... what does that say to you?
