It is true that this may be what life would be like with her; however, when I was younger… I had lived through a terrible childhood & a 5 year relationship w/someone that (in retrospect) was likely bi-polar I, had a gambling problem, etc. Then I met my husband. I was only in my early twenties. We were completely different. He was from a very stable family & had not been in a serious relationship. We married. Within a year, I found myself wanting to argue (because that was what I had learned to communicate). I also had terrible mood swings for no apparent reason – I thought I was bi-polar. Fortunately, my mood swings were due to a thyroid problem that was easily treated with medication. Life changing. My life stablized, but I still found myself wanting to argue as I considered this communication. After a couple years, I found I no longer had the need to “argue” to communicate. My husband was so patient, kind, and gentle. He was always there no matter how much I “argued”. He taught me to be patient and that it was not necessary to argue as a lifestyle. I am so thankful. This was my experience. My experience was compounded with a physical illness that was treatable and I wanted to have the best quality life possible. I had been in therapy in order to not re-create the life I grew up with. I wanted a good life. I think it depends on what she wants and if she is willing to grow…and, of course, if you think that there is hope for change. Good luck.
