You seem to be very sensitive and fragile. You want to divorce your husband while you’re pregnant just because you are unable to cope with what he’s doing? This means that whenever you faced with A problem, you will always resort to running away from that problem. This will never solve your problems and you will keep on running for the rest of your life. You must be patient and tolerant and try to advise him in diplomatic and respectful way. Try to choose the right time for your advice and to always weigh the consequences. Work hard on improving your Iman and increasing your knowledge of the quran and the sunnah. Make a lot of Duaa and Allah will answer your Duaa.
