Visitation Question!


Registered Users (C)
I'm an American woman who has been dating a British man for 2 years.
I visited him in England for a week and came back to America for 2 months.
Then I visited him again for 3 months.
Then he came to America to visit me for 3 months.
I then went back to visit him again for 6 months.
He then came to visit me for 3 months.
We then both went to Canada for 6 months.
All of these visits were made without a Visa.
Should I be concerned that they won't let me in, and if so, how can I ensure that they will allow me to enter the UK?
