Tim I meant that I don't approve of @Sara2001's parents encouraging them to develop in a direction which would make it so much easier for an abusive partner to manipulate them into staying.
Under the assumption @Sara2001 bf is abusive it is correct. But this isn't happen, because they discuss everything in detail and open which you not often find in a relation.
Both are adults and decide by them self what they want do do and what not. Provided that everyone can decide freely at any time, I support this wholeheartedly. I think, who am that I can judge whether it is wrong or right for them. They need to know that.
Sara2001 In addition to that I think that anything has risk and as long as it is a known and risk that can be calculated, everything is fine.
The problem is to see what the whole risk it. Some time it can have a long time impact which is not easily visible at the moment. Especially with health related impacts.
