I have to tell you that your post is barely ingelligible. Some punctuation would have helped considerably.

What I'm understanding is that you have two co-workers who started dating, developed some problems, and both were confiding in you their version of whatever conflicts the two of them had. The male co-worker stopped talking to you and you made a comment about it to the other employee involved in this situation.

No, you certainly didn't do anything that can be construed as having caused a hostile work environment in the legal meaning of that term. If your employer objects to something you said or your involvement in this personal relationship mess between these two co-workers, they're free to discipline you though.

In the future, I expect you'll find it best either not to get too involved with co-workers' personal problems or at least limit the discussions to off-work time.
