Would you turn up to a big birthday party (with food and drink) without a birthday card let alone a present?

My husband and I had a very special joint birthday party. Solely our choice, but cost us a fortune with band, reception drink and a knife & fork buffet in a lovely golf club setting. We invited all our lovely friends and family. I was quite happy not to invite a particular person due to being a nasty type of person (very narrow minded opinions with no substance and very judgemental), however my husband knows her very placid husband and said he would like to invite him at least (so needed to invite both of them of course). So, I invited them, even though not wanting to at all. The awful woman then kept mentioning to me about wanting to come but needing to leave early because of going away the next morning. I told her politely not to bother coming if a problem, but she kept insisting, in front of others that I hadn't invited, that they would come (as if she was doing us a favour!!). In the end, I just went along with the flow and accepted they were both coming. I asked my husband the next morning if he had spoken to the husband - he said he nodded at the husband only, as he was tucking in to a big plate of food at the time. I never spoke to the wife, as she just seemed to be enjoying herself too. Not that we were expecting any presents or cards, but all of our friends had bought us lovely gifts or clubbed together to give us sometime. Looking at the complete list of 170 friends, this was the only couple that never even got us a card. I feel very disapointed at the prinicple and unfortunately this has upset me more than anything. I will be giving a lot of our money away to charity and I am certainly not a greedy or needy person, but I feel taken advantage of a 'taker' in life and want to confront her, as I feel she has got away with this awful behaviour for too long (with others too). Do you think she is abnormal - how shall I confront her and her selfish taking bahaviour. At the end of the day, if she didn't want to get us a birthday card, she needn't of turned up for the free drink and food. She is one of lifes complete takers, but has done absolutely nothing herself and no-one has ever been invited around to her house for a cup of tea!. Have any of you experienced the same and how did you deal with this sort of character. I feel I need to let her know that I know she is one of lifes takers in life and totally fall out with her to teach her that you have certain morals in life - and she has none. Thanks in advance for your mature advice.
