Before considering answering your poll I have a question.
At what point *should* you stop trying to help a child learn to walk?
When they fall the first time and start crying?
When they fall the second time and start crying?
After a specified number of falls?
I'm not being sarcastic at all.
But I am trying to reframe your question into a less volatile subject so you can see how it may appear to others.
For me-I can't imagine walking out on someone I love because they are struggling to find their way to being comfortable and accepting.
It took my husband over 3 years after I cheated on him to get to the point where he's able to reasonably accept that I am poly (and the whole time my bf has lived with us as well).
There was a lot of discomfort.
But it has been more than worth it.
The process of growing and learning and changing IS life. It's what makes a life, well... lived.
Likewise, living a life together is what makes a relationship a relationship... the relating to one another.
Sometimes it's hard. Sometimes it's easy.
There is no hard and fast rule for "when" it's been "long enough".
