You know it's my pet hate sitting in the passenger side of a car with a person of the opposite gender when only the two of us are in the car, I'd rather take the bus!
I really do not know how you should approach this. Is there a person whom your husband looks up too?
You need an objective (muslim) third party who will sit and mediate between your husband and you, and your husband has to see that socialising with non-mahram women is not on, he wants to socialise and talk, he has you, he can go out with you and his friends.
And quite honestly if he has said he likes this woman, he's got to leave her well alone and start walking to work, or taking the bus or the train or the tube or he could look for another job. Altho that last is insane, one cannot go thro life unable to control ones nafs, that way lies madness.
And make lots of dua, I dunno about patience mine ran out on me a while back!
Wassalaam
