Hello foxy, sorry to here that youve had to put up with this.
My father was in the R.A.F served his full time, he was quite violent to us kids, but we loved him so much it was all forgiven and forgotton untill later years. That was part of growing up in a forces back ground, and you will find it happens alot in the police force as well.
To answer your question , im not too sure in this day and age, it probably wont if he only had a caution, and very lucky he was too to get away with that.
If he doesnt get the promotion on his merits then thats his fault and he needs to own that one.You didnt make him hit you, that was his choice,it has nt ruined his career.
I wonder why the millitry police didnt get involved because usually they keep there problems with there own.
Hes making you feel guilty because thats what abussive people do.You need to let him know that this is not acceptable or if you have other friends wifes or husbands in the raf then try to talk to them if you can, i understand how difficult it must be for you.
