My question involves criminal law for the state of: Indiana

My name is Jesse, and I'm a 19 year old girl (20 in Jan. 2010), dating a 16 year old boy (17 in Sept. 2009). We have done nothing that could be considered even remotely sexual, and don't plan to unless we're married. But, his mom and step dad think I'm too old for him, and that we'll get in trouble with the law because "things happen" (their words, not mine, I have more confidence in my morals). They say that the age of consent being 16 only applies to children who's parents sign for emancipation, which they absolutely will not do.

So, I decided to post my problem here, and hope someone might be able to point out any laws there may be against dating, and if there are none, at least offer advice.

Thanks.
