Too bad advice is considered flaming. Like I said, it was not meant to be disrespectful. And, it apparently was general advice. Was not directed to you. It was a suggestion to what the problem might be. Sometimes relationships have problems due to immaturity or individuals having a bad attitude such as being bitchy.
It is not that it was removed. Said nothing bad.
But it apparently upset you. You probably complained and they removed it.
It happens all the time,
I do not take it personal. As should you.
The word Mature is not the right one to use, but then again it might be. If an adult talks to a child like an adult. Though the advice might be good advice, it could be seen as an immature approach since it is a child they are talking to.
I will give you advice that is not so direct, like I said. Did not meant to be disrespectful.
When someone says that they cant be themselves around others there are generally two basic reasons. In your case, either he is afraid you will get too emotional and are to quick to pass judgment. A common problem. It is best to let the other talk, process the information.
Now you might not be one to be quick to judge. If that is the case. Then you need to clearly let him understand in an understanding and compassionate manor. Without using blame, this way he does not need to be afraid to be open with you. At that point, if that is the reason, he as you will need to grow up. Relationships are about growing. All the time.
