Firstly, sometimes just talking things out will help you settle your mind more, even if the person doesn't say much in return or you don't take the advice.

Second, advice should always be a welcome thing. Especially from someone you respect, but regardless even people you don't like or know can utter a true statement. Listen to what they have to say and weigh it in your mind. Unless you are a sheep you will only follow what MAKES SENSE, not what someone suggested and now you just HAVE to do it. If they realize something you don't, it's good that you hear it. Ignoring advice is typically just denial.

you know that the person from whom you are seeking advice will not give you a straight answer. By questnonig you and making observations he/she should lead you to realise the solution on your own, instead of making the decision for you.

This is a problematic issue that seems to be growing. People in somewhat serious relationships telling their friends everything about it. Relationships should be private and a lot of times the other partner does not want everything discussed with friends. Women do this crap all the time. They get together with their friends and nit pick each others spouses/boyfriends. This can never lead to anything good. It also isn't fair. It is never nice to talk behind someones back, especially someone you love. You know what is best for you, you don't need other people, who most likely have far less insight into the problem then you do, dictating what to do in your relationship. Like I said, keep the details private, it isn't nice to gossip about a loved one.
