As Dry-Heat said...I would (did) file for D...this doesn't necessarily mean that it will become final...but it lends teeth to your words...you can't continue with this treatment...and unless he gets REAL help you can't continue with him...
I understand how scared you are...I was too...I had been with H and dependant on him since I was 15...at 42 he walked out on me and the kids...left me with no job, no home, nothing...I started from the ground up...I was scared but the more I made myself accomplish the more confident I became in myself...that WE would make it...the kids and I would be fine...it didn't mean that I no longer loved or cared about H...but I couldn't do anything to help him...just as he really couldn't do anything to help me...I had to do it myself...
Now is your time...you can do it...set out a plan...go to see about what programs as a single parent you are eligable for...if you need more education see if that can be arranged and paid for with public assistance...ask around of other single moms...ask for help!...you will find your strength to get through this...
Moving on with your life doesn't mean moving on with another man...you have LOTS of time...get yourself together and then you can evaluate the whole situation with you and H then...if he is getting REAL help there is not hurry in finishing the D...if not you can decide what and how you want to do things...this is YOUR life too...I know my H always said if he didn't get it together before the D was final there was no law that said we couldn't remarry...as long as I was still available...he did get it together...he had many many issues to deal with...it was a LONG road...
Lisa...you can do it...your children are your strength right now...let H go and get on with your life...if he figures things out then fine...if not you are on with your life...no more time wasted in limbo...
