it's not healthy...
It's not very healthy to talk crap about your lover to your friends. Afterall, he is your lover and we love our lovers
So don't do it unless there is a serious problem in your relationship, which you should confide in very few and not blast it to the universe. Rules Girls love their men for all their faults, so don't be so hard on him behind his back, it's really not good for your relationship.
Talk WITH him not ABOUT him when you have a problem.
