In an LTR with a chick whos been constantly shit testing. We dont live together. Im going through some court issues and have been studying hard for a new career while working 100 hour weeks. Im finding it hard at times to maintain my frame with her when shes shit testing me recently and I believe its attributed to the stress, loss of sleep and over working...im just getting pissed when shes fucking with me.

Any tips on how to relax a bit more instead of responding with my anger?

For instance, we usually talk before she goes to work today and she made up a scenario that she couldnt talk because her roomates bf's friend is sleeping on her couch in her room and I just got frustrated cause she was wasting my time with text messaging and told her to fuck off and stop wasting my time with bullshit lol....definitely lost my frame.
