marriage as a young revert

Hello all, I am currently 19, and I reverted about 3 years ago, but I have kept it low-key (meaning only my close family knows). When my family initially found out, they were shocked and upset at me, but they eventually calmed down and have semi-accepted my decision. Now, the discussion of marriage came up today, and I don't plan on getting married anytime soon (probably in some years from now). Still, the consensus among my family is that if I choose to marry a believer woman, then they will cut all ties with me, not go to my wedding, etc. What should I do? As I feel like Islam as a belief system truly speaks to me and overall is the most balanced, fair and just moral and philosophical system rather than something fallible humans created. I mean, while yes, I do want to pursue my newfound belief fully and that means marrying a fellow believer, I love my family equally as much. If I were ever truly cut off from them, I wouldn't know what to do, as I fear it would create some huge vacuum in my heart as well as theirs, and I don't want that. It would be a great help if someone with more experience or knowledge than I had gave some advice.
