Mother-in-law having hurt feelings because husband & I eloped?

[Sophie]

That shouldn't be surprising, you say. However, BEFORE the wedding, she was very supportive. In fact, she was the one who suggested that we elope in the first place, because she knew how tight our finances were and that I would freak out when I would find out how much the costs of an actual wedding was. She even threw a huge engagement party in her backyard so families would have a chance to get together and celebrate. 2 weeks ago, my husband and I eloped to the local Justice Of Peace with just our two witnesses and a photographer. We then had a carriage ride, went to a nice restaurant, and made sure to have tons of pictures taken. We made albums for everyone who asked for one. And that's when my mother-in-law started to freak out. She saw the pictures and realized she would have wanted to be there. She even said that we could have just invited the parents to court, that they would have gone home after and let us have our fun day downtown with our friends. But it's done it's done, there's no turning back in time possible, and we have no regrets on how we have done things. Everyone else in both families thinks we were smart and have done the right thing. What could my husband and I do to alleviate those hurt feelings?
