I would agree with the rest that it is definately time to do something...

You may have already done this and it hasn't worked which is why you are to your wits end...

Wouldn't a candid sit down conversation be better...lay out the rules of the house (together)...have your thoughts prepared...maybe jointly you can avoid what will be a relationship breaker...just a thought?

I'm most concerned about your grandson...court may not see it your way...if you loose and don't get costudy...you will for sure loose your a relationship with your granson as you will need to go through his mother (your daughter) to see him again...and of course there probably will be little or no relationship with your daughter...

I'm sorry for this awful mess...
