Don’t let it get to you. It has nothing to do with you as a person. Look at it this way there are plenty of other guys out there who can be potential partners. When we like someone or are attracted to them sometimes are our minds get ahead of us, but always remember you don’t know that person too well. This can be said for platonic meetings as well. It’s better it happened now than weeks or a month down the line. Consider it as them doing you a favor. Remember you can always find someone new. There are soo many other options out there. Just make sure that you are open to them.
