Contemplating getting remarried

This is really long but I just need advice.

I'm currently 21 years old. Living with my boyfriend, my cat and his two cats. So I divorced my ex husband back in Dec 2019 and started dating my new boyfriend in February 2020. We are both in the USAF. I know. Sounds fast but my marriage ended months prior to all this and just wasn't a good relationship. My new boyfriend had asked me if I'd consider getting remarried. I asked him to give me time and think. And after about 10 minutes I knew that I'd want to marry him. He gave me reassurance that he wouldn't be like my ex and is just wonderful to me and my cat. So I asked my dad if I can bring him home and they can meet. Not to ask for his blessing but just to meet. My dad does not want me getting married for about 3-4 years. And I respect that. My first marriage lasted about 3 months and I did it out of spite and not really considering anything. I fear that I might get orders to a different place and my boyfriend and I would have to separate and eventually break up. I absolutely love this man. I'm not sure what I should do. I want to talk to my dad about it more and see if in the next year he'll allow it if I planned it and showed him how much better everything is. Or should I just tell my boyfriend we have to wait? I'm willing to wait. I'd wait a million years for this man. But long distance does a lot on a relationship. Please help.
