Dear,
Yes, you are right!
It's sad but true but when a human
says it's over then it's over and usully the friendship is also come to and end.
It's sad when thinking that we the persons was intimate to each others and loved each others.
For me friendship and love is forever and nothing that comes and goes.
If a person understand that her or she is not comfortable and finds out something when being together with a partner of course then it's better to break up than try to live unhappy in a relationship.
But therefore it's important to learn about each other before starting a relationship and even talk about like and dislike.
Many relationships has ended when a male says to his wife.
I like big boobs when the wife has small boobs.
Or when the wife says I like big dicks and the husband has a little dick. Or saying I like "this" when the other partner doesn't like it or share the same interest.
Here in Sweden we say.
"Kids with the same interest playes best together"
passionate kiss to you!
