I can personally see that you were really, really hurt and angry..which I think that you do have the right to be angry about this..but, also, I do think that you should sit down and talk to him..with regards to him not fully knowing your father very well, and also going behind YOUR back..as well as talking about a highly personal relationship issue with your father!
I think, and this is MY own view here..that your hubby is just NOT thinking this whole issue throughly..and also, it sounds like he feels frustrated..not just with you and he in the relationship..but, with himself..he feels insecure...in the relationship...I think that it can be really hard if you are in some ways alone..and you don't have a friend or close friend to talk to..with regards to the problems and issues..ya know, like a close male friend..(You don't mention this ,,,so I am assuming that this could be somewhat of an issue for him) and I have also been in his situation..and I can totally understand..when you need a male friend to talk out these issues..and or a female friend..(because you don't have to just have a male friend if you happen to be a guy, and the same for you, as a female!)
I ended a long friendship,(37+ years) with somebody and I now don't have a super close friend to talk to about my troubles..I have a new friend..but, I do NOT push my issues on to her!
Maybe your hubby needs a friend..but, your dad...should NOT be the one to talk to about ...I feel that this gets way too personal...for all of you..and that stuff, should be told to either a therapist or a friend..but, NOT somebody in the family!
I used to tell my parents stuff..about my boyfriend stuff..but, now being married..I try hard never to!
It feels wrong! I also feel that if I decided to get serious and get married..then, I must be much more of a "grown up" and that I should be able to handle myself, better! (Maybe that is an illusion...but, I still tend to think that way!)
I hope that this might help you, anyhow!
But, whatever you do...don't come down too rough on your hubby..talk to him..and tell him..that you would much prefer him to NOT speak about your marital issues with your father..because it is way too personal...for his and your issues to be on your dad's mind...and to tell a friend or you..about what is bothering him!!
Good luck!
