And I think you absolutely made the right decision. Just because you aren't physically there doesn't mean you have no parental rights, unless you have relinquished those rights to allow someone else to file for legal adoption. Again, not knowing the circumstances I can't really go into too much depth here, but an open line of communication is absolutely key. You should be able to communicate your wishes for your daughter and he should be receptive enough to at least hear you out. Whether or not he agrees with you and what he ultimately does about the situation is out of your control, but you can at least know that you did what you can. Keep on your daughter about it without coming across as a harping nag. Make sure she knows that you aren't happy about her decision to smoke because you're concerned about her health and well-being. 16 is a tough age because it's when teenagers seem to think they know everything there is to know about the world... Somewhere around 25 or 30, she'll figure out that she really had no idea and mom was right all along... Just hang in there and know that she loves you, even when she says "I hate you" it doesn't mean that she hates you. She still loves you, just hates that she is not in control of her life yet...
