The best advice I can give you (based on years as a sec. in this field) is this... GET ALONG!!!!! You do NOT have to like each other, but you do have to remain civil and cooperative. Once you begin fighting it has a snowball effect. Remember...he was good enough to love... It is the behavior that is bad - not him. If you approach the subject of dropping off kids, in the same manner you would have when you were both in love, you will get much further than trying to "force" him to do it. Just say something like - Look, I need some help here...what can we do to help each other and our children...
Remember - the best parent is one that seperates her own selfish-hatred of her/his ex, from the love of their children and the love that those same children have for their father/mother. Always-Always ask yourself...do I hate/dislike my ex more than I love my children?? The answer should always be a resounding NO!
If you need anything, email me back and I will do what I can. Sometimes those who are not emotionally involved can give the best - most common sense advice.
As for attorneys... the tales I could tell you about certain ones!!!! There are many ways to do this...you could both agree to work it out together, i.e., come to your own agreement, then have it put in writing. After that you would both have an attorney review it and have it entered. Yes, if you let the attorneys "work it out" it will cost you much much more - and consider this: If it costs you $10k to get $5k, what have you gained??? There are some good divorce attorneys, but unfortunately - there are many more bad ones!!
