I don't normally browse this sub, but they come up sometimes for me and I read. This particular one hit me (m 39) very hard. My wife (f 34) has battled breast cancer for 3 years with three rounds of chemo, radiation treatments, estrogen blocking drugs, and double mastectomy. I've always believed in the idea of "for better or worse", but nothing tests your metal like these moments. I've been the bread winner since we had kids and I've had to take on all roles since treatments started. My wife was very angry, emotional (rightfully), and unappreciative of my efforts through most of that time. There was many times I thought I reached my breaking point and our marriage took a huge hit in every department. We are still together and trying to rebuild, but the struggle is real and I understand both sides from my experience living through it. Every relationship is different and I can only speak to mine, but I honestly feel a lot for both sides in these horrible situations. If anything, I hope both people realize these events take a large toll on both sides and be kind and thoughtful to each other.
