I have been living with my new partner for about 6 months. We met not long after the end of my 20 year relationship. It's great in many ways, we enjoy the same things and laugh lots. He comes with some issues (don't we all) but we begun with a promise to always communicate and to keep what we thought as a wonderful second chance (we are both in our fifties) healthy. But I have discovered he has a hugely unreasonable side. Going off the deep end very quickly indeed and descending into a sort of 'pity me, I've had a terrible day, you're really stressing me out, I feel sick" whining rant. It's awful - like some angry wailing teenager. He will not be reasonable when like this and everything becomes my fault. I am actually a very reasonable and communicative person, so I find this behaviour really shocking.
Anyone else experienced this?
