Is it normal that ur type change suddenly?

My taste in men changed suddenly! I used to like some kind of men! I used to date that type of men ONLY. And from ONE country.. I was against the idea to change my mind or the type of men.

Suddenly am not attracted to that type anymore! I was serious but they were players! Most of them. And the last one was a narcissist and discarded me.

Am 30, I feel am looking now for a family man. Am tired of wasting my time.

So now am thinking to leave the country where am living. I don’t know I feel somth is off.

Is it normal?
