To tack on to some already great points... Usually, parents try and look out for their kids, in some form or another. Yeah, I know there's exceptions, but in your case I'm pretty sure they want the best for you. That said, your dad isn't telling you not to join because it's in your best interest. He's telling you because he's being a bit selfish. And it's totally understandable when you see the news day in and day out. He's worried about you, and doesn't want to lose you, whether it's to another "family" or worse (and I think you know what I mean). I'm just saying this based off what you've posted here, so if your dad has a history w/ the service, there might be more there, but overall, that's my take.
As for joining...There are times when it's going to suck. It's hard work, no matter what people tell you. You're going to study your butt off for the next 3 years, and once you're comfortable in your platform (speaking of aviation here), you're going to have to continue to keep your nose in the books, because there's so much info to stay current on (and nuggets that are asking you questions). Deployments are long. You're away from your family during important times (holidays, births, deaths, etc). But...
There's so much to get out of the experience. Whatever you thought your limits were, you'll probably find that they will be expanded (that's a good thing). They hand you a multimillion dollar piece of hardware, tell you what you need to do, and then let you go. It's totally up to you and your crew to make it happen. Talk about freedom. The benefits (money-wise) are pretty substantial now. Medical care alone is a huge thing not to be worrying about. And then there's the people. They're just like you. They want to do their job and have fun. I'd recommend you head over to the "Why Naval Aviation is good" thread. With all the sucky stuff you have to put up with, there's all that stuff in that thread that you get to experience.
As for education, if you go OCS, you'll have something that many don't in the officer corps. A GI Bill to fall back on. Guys coming from ROTC scholarships and the academies don't have that, so the government will want something for their further degree aspirations. With the GI Bill, you're already starting out w/ "free" money.
So, in summary, if you truly want it and are ready to work hard with huge payoffs, go for it. Your family will come around.
