Has anyone went to couples therapy?!

My bf and I have been together for 8 years off and on. Mostly on more than off. If we did break up it was a very short while. Anyways we've been having issues again. I mentioned couples therapy but I was wanting to know if anyone else has went wit their SO and did it help or make things worse?? I need input. No bashing. She have a 18 month old together as well.
