Just my 2 cents

Don't ignore the red flags. They only get worse.

They are on their very best behavior the first year or so.

If they show you who they are believe them.

Behavior is a language. They can talk all they want and say so much stuff but don't believe it until you see it. A lot of them are notorious for this.

At least date 2yrs before moving in together. It is harder to kick them out or vice versa. The longer you stay the harder to leave.

Live with them before marriage and see if you can still stand each other for at least a year.

If the sex is bad or average it most likely won't get better.

See how they handle finances.

Learn from my mistakes. Lol 😆
