I can tell that you like him, and I would have suggested that you wait and let him make the first move instead of giving him the letter expressing your feelings, but since you did….. his non-response means he’s not interested. 😳 I know that’s disappointing, but the good news is that you haven’t wasted a lot of time on someone and the fact that he’s being clear with his silence, while disappointing, is a good hint that you should move on. Vacations can be like an altered reality because you’re not in your home and you’re not in your routine and it seems like anything is possible — and sometimes romances blossom on vacations, but they don’t make it back to your house with you! I think that his non-responsiveness is a big sign to you that this isn’t a romance that is going to go the distance from vacation to home.
So, don’t be lost. Be disappointed, but not for too long. Instead, look for someone to date who is local and who, if interested, really wants to make things work. I hope that helps!
