Thanks for the kind words. It is good that your boyfriend is sticking by you. But it is ok to "pick and choose" from whatever he says to heart. The "get over it" attitude is the default response for a lot of guys in this situation simply because they don't know what to say or how to act, and they may even feel some guilt and sadness themselves that they do not know how to fully express.
I think this is especially true of Hindu men (I'm guessing your boyfriend is), because I have also been in a previous relationship with one (Nepalese) - their family values are very traditional and ingrained, and children out of wedlock is frowned upon. I suggest that you try to explain to him that it will take some time to make the emotional (and physical) adjustment and to please be understanding and patient.
My thoughts are with you, I was in exactly the same position with regards to not having someone available to speak to candidly without fear of judgement and living in a foreign country. However you have a bigger challenge living in such a radically different culture. I would strongly urge you to seek out someone to talk to, only if it is for a few sessions. Sometimes its good to just get it all out in one go. I did a quick internet search and I found the Indian Psychologists Association - http://www.iacp.in/index.htm . They may be a good place to start if you want to try that avenue. Try not to be discouraged by negative reactions, keep going until you find someone. Maybe even ask for a referral or suggestions from a social group in the British Embassy? I came across a few british expat sites, here is one for india: http://brit.meetup.com/cities/in/
You also face a big challenge having to work in a service industry and trying to put on a "brave face" every day. I was lucky in that I could just hide in my office under my desk! If it is available to you, I would also suggest taking one or two days off work just to take some time for yourself as long as you don't isolate yourself for too long. Don't place pressure on yourself to 'get over' this, try to cut down as many work, social or other stress-inducing obligations as you can.
If there's one thing I've learned, its that in times of stress, proper nutrition is vital. Getting the proper nutrients, (espcially tryptophan and glutomate which stimulate neural transmitters including serotonin), drinking water and getting some exposure to sun light are all good non-drug therapy.
I hope you return to keep us updated. I've signed off to be notified of any replies here, and so I'm here to offer advice or just "listen".
