A Match I Caused to Fall Through

Hello, I have a 22-year-old brother in the Hebron Yeshiva who has started hearing shidduchim. He is very successful, wise, kind-hearted, charismatic, handsome, tall, beloved by people and rabbis—a paragon of virtues. He wanted to study, so he waited until the end of the fifth year to start listening. We are a family with an open religious style, serious and combining Torah and work, so in our sector, my brother's style (serious yet open) is very rare. He was offered a good, wise, and very beautiful girl, very successful, the best in every way, but they are offering a relatively small amount of money compared to what we expected, and she is a bit more modern than him. I am very involved and convinced my parents to wait; they were very hesitant but listened to me. A week ago, the girl got engaged to a good friend of my brother. In the meantime, it's been four months with no proposal in this style (it's very hard to find in this style). My parents find it very difficult; my brother is not an ordinary guy, and he really needs a successful girl too. I have a huge conscience all the time, I'm afraid my brother missed his match perhaps because of me, that he will find something less good now (because there really isn't in our sector, it's a very specific and difficult style). I'm trying to understand, can such a case happen? She seemed so suitable to me in the picture, that I regretted it so much. I know everything is from Heaven, but I know that maybe in shidduchim there is an issue of effort, and I intervened a bit (I thought he didn't need to compromise on this at this stage). And my brother fully trusts me and our parents (I know a lot and generally understand people very well), and I feel that I simply made a mistake, I would be happy to receive answers. It should be noted that my brother is very easy-going and fully trusts us, but my mother finds it very hard that now there is nothing suitable.

Hello and blessings 

There is a possibility of losing the intended match.

I don't think this is the case, because there was a decision made, perhaps mistaken, but there is no claim against you. 

Pray that the right match will come.
