The Bombshell is likely right but I think you Timothy will find out for yourself, I think to make it work would require deep soul searching to find out why the last breakup and see the error that broke you up and be smart enough to know if you or her can change your ways if need be or smart enough to walk away..
What is it about you that he hates ? is it the way you wear your pants ? your do nothing way of life ? does he think she can do better ? Whatever the reason use to make yourself a better man
ok you know sometimes Dad's just don't like the idea of their daughters being with anyone .
Stop doing whatever it is you're doing that makes him hate you.
Well if you've broken up once, then why do you even want to get together again? If it failed once, why wouldn't it fail again?
