I am so sorry that you are going through this! I don't know if you would like my opinion, but I am a non-Muslim from the western world and what you have described is not acceptable in my eyes. The argument that you have to be a certain way (less religious) because you live in Western country is opposite of why these countries have certain freedoms. You should be free to express your religion, not conforming to the way people around you are acting. Yes, if he works with women, he will have to talk with women and be polite and professional with them. He might even eat lunch with his co-workers as a group. However, depending on his job, he does not need to be alone with them to take extra breaks to be with them to be accepted in western culture. Emailing someone more than just a simple "How are you?" after you move is not normal. This does not sound professional.
From what you are describing, it sounds like you don't feel like he is caring for you. I don't know how you want to handle this, but I would suggest finding a trusted person who can come and talk to you both- counselor, religious leader, trusted friend. If he tells you to see a counselor for you "craziness" maybe you can try to go together.
