Like 12 inches. Oh wait, that wasn't what you were asking. Never mind... :-)
Too long was before the children.
Now he thinks he has you forever, and why get married?
Hell, just go buy yourself a damned ring and pretend.
WTF difference does it make now?
I don't think a piece of paper makes anyone more commited. 8 years, you live together, and have 2 children together, sounds pretty commited to me. What will really change for you if you marry?
8 years!! I mean, wtf? Might as well get married. Do you know why he hasn't proposed yet? Have you tried to propose to him?
You already have kids.....why bother signing papers now? If he hasn't been unfaithful to you I would think he is committed.
you'll never get married but you are practically married already :)
