Yeah, the source of support is important. I've noticed that if I have been talking to friends who are saying - I don't know why you put up with this etc. - I start to get all fired up.
The big thing I say to myself is if I am angry, the answer is do nothing, stew for a couple of days or whatever. Most times I process things and am glad not to have done anything.
The other thing to maybe consider is writing to your W but not send it. Maybe have an 'angry text book' and whenever you get the urge, put your angry text or note in there. It gets it out from your mind and written - and hopefully the impulse is assauged but the 'heat of the moment' message is not sent..
