A game plan of what you want in terms of marriage, kids, and where you want to be in 10yrs is great to attract like-minded partners. 10yrs ago I dated someone and was adamant I didn’t want marriage or kids. 5yrs ago I dated someone and was adamant I wanted both. I hadn’t changed. I could take or leave marriage and a second set of kids. What made me want it or not was the partner. I needed to believe their goal was me, not that fairytale. I’ve also met people who can’t legally remarry. There are alternate ways to show commitment. All that to say, “Probably” is usually enough! And your feelings may change over time e.g., as you get over your anger at being a single parent when you planned to do this as a duo, as your kids get older and you’re closer to an “empty nest”.
