If your gut is telling you that there is something wrong, Most generally there is. Reason I say that is because most of the time, Evidence will show up that confirms your deep inner suspicions. But then again, Others opinions can sometimes bring in some clarity for those who are denying what their instincts are trying to tell them. Just proceed with caution.
Trust your gut... a lot of people seek advice because they sense something wrong in the relationship. Advice can be helpful in trying to figure out what to do. Just because we know something is wrong doesn't mean we know how to handle it, and we seek advice if we need to look at things from different perspectives. It helps us understand, and then our personal feelings and instincts can lead us to the best path to take.
Like, if you get three different opinions for how to handle a situation, I would always go with the one that feels right to me, even if a different opinion was more popular with others. The option that makes you feel the most happy, free, and guiltless is probably the one to take.
in my opinion the best answer is that you should listen to both. Don't let others guide you in life but don't ignore advice either. Humans are individuals, indeed. But individuals who are part of a group.
