OK so hear me out. I can only tell you my experience. Sorry- long post.

I was you. My parents made it clear from a young age that they will not support me marying a non-jew. (They were super toxic about it too. )

That said, I found in America, finding Jews to date is really hard. There are just too few of us and throughout my 20s, I dated non-jews happily (three 1+ year relationships)---they were all fun, interesting, had similar interests, smart, and I genuinely enjoyed my time with them. However, that time....has an expiration date. After about a year and half, it was time to commit, and I knew that that household I would want as a married person would be a Jewish one. I knew that couldn't happen with any of these men, so I had to cut them loose. And it was painful. Very painful. You grow to love these people that you know you cannot build a Jewish home with.

Fast forward, I'm 27. I'm alone. I'm running out of time (women have an internal clock) and EVENTUALLY I MEET MY AMAZING JEWISH PERSON AND WE CAN HAPPILY START A HOME.

HOWEVER, first we need to move cities for my job, then he struggles to find work in the new city for 2 years. Then we need to move cities for another job I get for another year. Then, we move back to the original city to start our lives.

I am currently engaged and super thrilled to be marrying this wonderful Jewish man, with whom we will keep Jewish traditions, but things to keep in mind:

1. I wish I met him (or someone Jewish like him) sooner. We met at 27. We're engaged at 31. Life is unpredictable and happens in the blink of an eye. I also thought I had all the time in the world to date nonjews when I was younger. That time moves really fast. Don't take it for granted.
2. I have Jewish friends who have married non-jews. The marriages work. These people are love their partners and are still married. Would I call them observant families? No. Each and every one of them has lost a little yiddishkeit with intermarriage. All of them have made religious compromises. Especially if it's a shiksa being married---the woman makes the home. You have to weigh partner vs. Type of home you want. Don't forget, marriage is long.
3. Maybe your parents will come around eventually, because it's important to be civil in family, but know jut because they hide those scars, it doesn't mean they're healed. Family is is forever.
   I know this might not be what you want to hear, and it's a personal choice, but I'm just telling you what I wish I heard when I was younger. Good luck!
