tldr; my life is a mess

I started dating my fiance in July 2014 which was long distance up until October 2016 when he flew from Conneticut to California to not only meet me for the first time in person but also leave everything behind to move in with me, got engaged June 2017, and our wedding ideas are a mess. I would walk down to the court house and marry him tomorrow but my family is so judgmental of the fact that we met online and dated long distance for two years and decided to say f it all and instead of paying about 800 bucks on a round trip plane ticket to meet and then have to say goodbye, we would spend 300 bucks for one way and move in together. Which I totally understand because we could have not worked out, which could still be a possibility yknow you never know, but we did. This past year together in person with our two beautiful cat sons has been the best year of my life. I know if I just go get married how I want my family is never going to let me live it down and I'll get an ear full from my mother especially 😒😒

Am I moving too fast in my relationship and should postpone getting married or follow the way my heart feels?
