Hi... We don't have any control over others choices and actions. We can only control our own.
As per your question. Yes, it is a normal behaviour. People do lie to each other and sometimes overlap relationships.
Especially, people with poor emotional background and lack of moral code involve in such behaviours often.
The old boyfriend needs to confront her with the facts and ask her to make a clear choice. If she is unable to do so or again lies about it and continues relationship with both. The only boyfriend must end this relationship voluntarily.
