That’s really shit news. A friend of mine went through it this time last year. Her partner wasn’t really interested in it much to my annoyance (they’re only together as a front for the kids now) but it turned out the lump was a peice of detached tissue and would sort itself out in time.
Give your wife all the support she needs but make sure you get the support you need too from outside of the immediate family circle as well. There’s always someone willing to just listen be it someone here (im always happy to listen), a professional or even one of your riding buddies.
This habit us blokes have of bottling sh*t like this up is really harmful to us.
Hope everything goes well today.
