My goodness, this a big topic.

Anyone who doesn't know to leave when they are being abused or worse has some serious psychological issues they need to work out first.

Personally, I don't believe in leaving when a relationship gets tough. It is more about maintaining a sense of harmony so you can always be open and honest with one another. Without that, it is a charade.

Edit: Apologies. Perhaps I was a bit hasty in jest. I will leave my original comment in-tact, as I did not realize until later that it was flagged. My poorly communicated meaning did not come across very well in writing, and may have been interpreted as offensive. An abusive relationship is no laughing matter. I sincerely hope anyone trapped in such a situation can find a safe way to peacefully find a way out, and get the help they need. In my second statement, I meant that a good relationship can be hard to find, and harder to hold onto. I have deep respect for people who are married for many years, and display the characteristics of a happy, healthy relationship. In no way did I intend my words to shame a person who has escaped, or wants to escape from an abusive relationship.

I am happy to communicate kindly. There will be no flag retaliation on my part. Only my desire to find better mutual respect and understanding.
