If someone doesn't seem to want you anymore, and that bothers you, just remember that it could be that you had different expectations of each other. Sometimes it's a misunderstanding of what you each wanted out of the relationship, or who you imagine the other to be, and so on.
As long as you conducted yourself in a manner which is good and right in your own eyes, maybe just chalk up the mismatch to an experience to learn from, and go on to the next relationship, or as I have done, just be happy on your own.
I am sorry that you are sad. Remember that it is temporary. Please reach out for any assistance that might help you feel better. Big hug.
Good bye every one.
Bye.. Come back soon...
Take care of yourself.
