Forget loyalty where is your bitachon???????
We forget that Hashem has a plan for us and it is not necessarily the plan that we had in mind! If things are going well with the shidduch you are in why risk it? What makes you so sure that if you dump it and go for the other one it will work out? You don’t have any guarantee that it will. It might be your dream date or dream shidduch but what makes you think you are the other person’s dream date or dream shidduch? For them you can be just another name on the list. But for the person you are currently dating you are the real deal.
People in shidduchim need to realize that when you are in middle of a shidduch you need to have blinders on. You can’t be looking at anyone else and you can’t be considering or thinking about anyone else. The rest of the world needs to become a blur. The only one you have to concentrate on is the other person in the shidduch. You need to decide if that person is going to be a good spouse and a good parent for your children. Is this person someone you can wake up every morning with? Does this person have the qualities you are looking for? Does this person share the same values with you? Are you attracted to this person? Can you live this person? Can you build a true home with him/her?
Forget about other prospects they are only a “possibility” the one you are with is a true probability and that is what counts. And please don’t forget if you hurt this person you are involved with that too has many consequences. Don’t propose to this girl if you don’t feel you can love her and make a true marriage with her. But don’t break off with her because you think there is something better out there for you. YOU are a fool if you do. You might be giving up the best thing in your life and throwing away your bashert that Hashem has sent you on a foolish whim that you fantasized about.
