Yes - by all means Al-Anon. Be aware that the way the majority of al-anon groups work, that no one there will tell you what to do. What they WILL do if you are willing to listen is share their experience, strength and hope. You may find that to be of value and use those experiences in your own life if you choose to do so. Also - NOTHING you can tell the other al-anons will come as a suprise to them. You will not shock or horrify them either. They know exactly what you've been through - they have been down that same road before.
Good luck. It's a program of attaction not promotion. No one will force you to come back if you don't want to. You will find wisdom there that you will find invaluable. Trust me on that.
