Quite honestly ime (49 lived a life!) And from discussion with others and on here...
Most men if they genuinely intend to marry you propose within 3 years - minor exception if you met around mid teen age
After that...he's just not that into you. Cut your losses and move on
Do you want dc if you don't already have them?
I’d feel like I’d have wasted my time
Sunk costs fallacy
Don't fall for it
You were quite young when you got together but at this point he needs to shit or get off the pot!
When I met my ex I was clear from the beginning (though didn't necessarily mean it would be with him) that I wasn't interested in wasting my time. That marriage and kids were important to me, I would not be having kids outside of marriage and I wanted 1st dc before 30 - I have gynae issues and had already had 1 mc when we met)
We didn't live together before marriage either which I also think helped actually, even though it wasn't a conscious decision.
We’ve both said we’d like children but maybe not for a couple of years yet. At least we agree on something
Op what is happening a LOT with men in younger generations than mine is they're stringing along their first serious relationship, wasting their fertile years (if you've never ttc before you've NO idea if it will happen quickly/easily for you, for women from age 30 fertility - quality and quantity starts to decline) then the relationship breaks down and they marry and impregnate the next woman very very quickly
DO NOT waste your fertile years this way
Happens a LOT
do you really want to risk NEVER being a mother cos he strings you along into your late 30's and then you don't have time to meet and develop a relationship with someone else?
Also educate yourself on the differences legally and financially between marriage and cohabiting
Having dc outside of marriage is risky in a number of legal and financial ways especially if there are any health complications thrown in either as part of ttc/pregnancy or once the child is born
