If I wanted to move out of state I would need to take tests in order to apply for work.

Sure, but you never know where your career will take you.

Traveling, I wouldn’t mind bringing the kids along. I’ve done my traveling already.. a lot actually

Travelling with kids is definitely not the same as travelling solo or as a couple. With kids, you can't be spontaneous, many destinations are out of question, and you'll be bound to flying during high season since they're in school.

You are 23, and Covid has been going on for 2 years....you're also still in school. How many international trips have you actually done?

What kind of choices would be limited by dating parent?

Lots of the things I've already mentioned. In terms of property....distance to ex partner, school district (if you're in a country where this is relevant). How you spend vacations/holidays, time with in-laws, ex and her family, how money will be handled given he already has kids etc. etc.

Timeline for kids. In a perfect world I would already be married by 26 latest 27. Which means I would already be done with school and have had a few years of work down. I would want kids before I’m 30. The timeline that I set for myself (before I met him) allows me to have a few years of work under me

Keep in mind, it can easily take 1 year or more to conceive. Also...will your bf get his sperm quality/quantity tested before you start conceiving? Again, him being older can have quite drastic consequences.

So finances will not be a issue.

So you're on the exact same page about how finances will be handled? You've discussed worst case scenarios (e.g. his ex losing her job, him losing his job)?
