I believe in my heart that priests can and do fall in love. However, a lot of them create a block to prevent these feelings from developing . I also believe that priests should be allowed to marry. There has been many a good man who did not enter the priesthood because of this restriction, and many more who left it.
Love is healthy and supportive.
Priests at one time in history were allowed to marry. Marriage also would prevent closet homosexuals from entering the priesthood rather than hiding under the cloth.
