Talking about engagement after 6 months?

[Wooooah]

Both mid 30s, have both said we'd like to be married, neither of us have children.
If I were younger I'd say it's ludicrous, but I'm just wondering what a realistic timeline is?
Don't live together. I don't want to fall into a pattern like I did with my ex of living together for years but the ex was never ready to get engaged.

It's good you're both on the same page. You've discussed marriage like adults and both want the same thing in the relationship.

Six months is too soon to get married (although there are exceptions) as you don't know each other and are both on your best behaviour.

Live with each other first and find out if he's respectful and considerate as a partner.

Met DH very early 30s. Engaged within 6 months, married within 14 months of meeting.
still married 20 odd years on.

What made it clear - arguments were resolved easily and maturely
No game playing - we were each clear and in agreement about what we wanted.

Baby was born 9 months after the wedding!
