Like 12 inches. Oh wait, that wasn't what you were asking. Never mind... :-)
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 :)
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?
