@TiffanyM96,
Hi TiffanyM,
I think I'm able to understand more or less about your situation and emotion, but I'm not quite sure what you are exactly looking for on the forum here, though you are saying you look for advice.
As I know, many women who prefered venting out than looking for a solution when they trapped themselves in some difficult situation. Please don't get me wrong. I'm talking about the psychological tendency of the difference between males and females. I don't judge what it is good or bad. I assume you are not an exception, as I can see the infatuation seems to be going to drive you crazy... You have to find someones who are safe to listen to, and help you sort the thing out.
I believe he is an excellent gentleman. Please don't feel bad about your feeling. It's normal for any person who is attracted to another wonderful person. It is like women would admire a brilliant diamond in a store, though it doesn't belong to them. It's okay you like him and are attracted to him, because he is charming. He should be proud of himself, as well as his wife who is so lucky to have such an attracting husband.
I assume almost every couple experiences the periods that are up and down. Even if he is attracted to you too, that doesn't mean he would forget his commitment to his marriage and responsibilities to his family. For any sake, please do put your emotional brake on him, before it derails, and don't let every passenager from your family to his family get hurt. You know this well too.
I understood you want too, but you just don't know how to put a brake on it, right? The moment your reason tells you should stop, another moment the infatuation are like huge waves engulf, overwhelm you, and you are being lost, being frustrated.
Now, I hope you can focus on the solution, and find a way out.
Here I would offer my suggestion again. Please cut off any contact with him and avoid seeing him at any occasions. Please find a man who is single to date no matter you are really interested in him or not. He could be a nice distraction. If you finally find out that you don't like him, then you can change another man. It's normal you will sorely miss the "Uncle" for at least a few months, but the infatuation is likely diluted bit by bit.
When your emotional tank is empty, it is hard for you to pull yourself out; but when it is full, or half-full. You would feel much better.
It is you who're the driver of your life train. I trust you that you still have the necessary reason to drive it back on the right track. You will have to learn "head over heart". Way to go!
All the best!
