Girlfriend Advice! Take It or Leave It?

Tasha Mack is back to her old ways. That is, she's dishing out advice to her girls on  how to handle their relationships.  She gave Chardonnay a few pointers on her relationship with Jason a few episodes back.  Then she warned Melanie about not supporting Derwin for the upcoming game.  It's nothing new, Tasha's been dishing advice on love and relationships (and everything else) since she met Melanie in the bathroom at the beginning of season 1.
The thing is, Tasha hasn't been lucky in love herself.

There's a lot of criticism about women taking advice from other women when it comes to problems with men.  Especially when the woman dishing the advice is single.  However, does one's relationship status preclude them from having insight into relationships?  Does being single mean that a woman's opinion on matters of the heart isn't of value or helpful?

Actually most of us give advice to others.  Because we don't have the emotion invested into the relationship, we have some clarity that allows us to look at the problem objectively.  Relationship status doesn't affect that.  I understand why some might be leery to take pointers from someone who isn't in a relationship. They may lack the experience to fully understand the issue.  However, I've met people who are in long-term relationships that I wouldn't listen to if they were on the best-seller's list.  Personally, I think you can learn something from anyone.

What's your take on it?  Would you take relationship advice from one of your single girlfriends?
