Thoughts on Lydia's Situation

I know it has been ruff times for the Bennets. I know I have hurt Jane really bad, I know Lizzie has just denied Mr. Darcy, and now, the youngest Bennet has eloped with, the one and only, Mr Wickham. From my point of view, it is understanding that Lydia has run off to get married when all Mrs. Bennet ever talks about is for her girls to get married. Why is this such a bad thing? Isn't this the what she wanted? I think Lydia is just confused and doesn't understand. I also feel that Wickam is a snake. He's just in it for all the wrong reasons.
