I'm not really into the whole marriage thing, I don't see how it really changes a relationship at all. So I'd be fine just 'dating' forever.
However those princess dresses are quite enticing...

Personally i think when it feels right, go for it ^^

My bf propased to me back in december weve been dating for 5 years already this year makes it 6

Honestly, it depends on the people involved. Some people get married after 2 months are happy, some wait 5 years and get married and are unhappy. It depends on the couple, Personally, a year and a half is around the time I always start feeling ok maybe, but that's just me. It depends on who you are with, if you are truely in love and are happy with the one you're with and have the finances, then it's good. But enjoy life while you can, you never know what will happen.

It's not about how long you have been together but you'd just feel it. If you can see yourself with him for the rest of your life and you think that you're ready to enter that kind of stage then there's no need for you to hesitate.

One thing I feel I need to add is that you should - or rather, NEED - to have lived with them for some time. You have to be aware of their flaws and idiosyncracies, and know you can accept them for it and love them anyway.

Though, personally, I don't feel like I'd ever have to be married. It just makes breaking up expensive. 

I'm not dating anyone - never have - and don't know anyone I'd date, but I do know a thing or two about relationships.
Basically everyone's come to the same conclusion: there's no set "right" time for every couple. Everyone's different, and everyone has different needs.

Personally, I have NO idea when I think I'll be ready to marry whoever I end up dating. That's not something I can know ahead of time. I know that I don't need to live with them. I don't need to date them for a certain amount of time before I'm open for marriage. When it's time, I'll just know.

However I do NOT want to date for a long time...no way I'm dating someone for years and years before we get married.

I'll share my parents' story here, cause it's so unusual but a good example. My dad had his eye on my mom for a while (a year, I think)until he could tell what kind of woman she really was (my dad's a surprisingly good judge of character; he's very discerning). Finally he approached her and asked to date her. She had only seen him around in church and such; she hardly knew him! But she felt like it was right, so she said yes. Two weeks they dated, and they just knew! He proposed after only that short amount of time, and she said yes!
They've been married 27 years, never been unfaithful, never been separated, never had a fight (yes, they argue, but they're calm about it and who doesn't?), raised me and my brothers well, and they're the best parents I could ever ask for.

So. There's an example: everyone's different, and there's not set time for couples to get engaged! Just take it at your own pace, don't rush into anything, and talk it over. And do NOT be afraid to say no if you're not ready!!

I fully agree with Eri-chan.

I also agree with galaxygirllove that you must accept your significant others' flaws, and possibly even love them for those imperfections.

I do not know when the time to get engaged is. It is dicey and very much subjective, that's for sure. Though I learned in a Sociology class that longer dating and engagement leads to happier couples/less divorce, in general, apparently. Makes some sense, after all, no need to rush!, right?

My boyfriend proposed on our 1 year anniversary. We had actually been talking about marriage for a few months before that. We were planning on getting married this year but now my boyfriend is at university so we can't afford it. We've been engaged for 2 years now! We lived together for 6 months soon after we first got together (before getting engaged) but then moved back with parents as I want to save up to buy somewhere to live so we can move straight in when married.

I have a friend who has been with her boyfriend for 6 years now and they're still not engaged because they don't want a long engagement. They want to save up until they can afford marriage but they have been living together for 2 or 3 years now so I don't see it makes much difference if they're engaged or married or neither.

I agree there is no set amount of time. I had a previous boyfriend that I had been dating for a year and I couldn't imagine ever marrying him. I believe you just know when it's "the one" and the time is right.

Marriage really isn't for me. I see the concept as more applying to say, someone who thinks it's morally wrong to not get married. It's really a culture thing. I see it more as just a slight tax break. Nothing more. That being said, I will put out there that if marriage DID hold any spiritual value for me, I would probably already be married/engaged. My bf and I have been together going on 2.5 years, and we know. We knew before we hit a year that we were meant for each other. I just feel completed by him, and vice versa. So understand that I am incredibly lucky, and also that time has nothing to do with it. It's what you feel inside you, that comfort that comes when you are with your "other half". If it's not there, then marriage just seems like a waste of time, money, and effort.
