How can I have a better relationship with my Dad?

I think you should just sit down and talk to him aout the situation . i dunno how old you are but its normal for teens and stuff to not get on with their parents mostly due to living with them and being around them all the time i think its bound to cause trnsion plus you want your own independance . anyways yeah talk to him about it and express how you feel but if he laughs or blackmails you or something then im sorry hes just not being a good dad . and maybe move out or just stick it out until your old enough to move out and try and keep a good relationship on the phone and visits often .
