I just post a reply to your other thread.....Honesty, I think there is nothing wrong with parents be good together and love each other....my parents were together for 40 years till my dad passed away!
you got to understand that there is a big difference of the love that your dad has towards you and the love that your dad has towards your mother.....your dad's love towards you is called "unconditional love" versus his love for your mother which is a "conditional love"....
people are different in their relationships and showing affections....however, if you feel this way, you should talk to your parents.....
and take it easy.....
