Phililpine Annulment

Can any kind person help myself and my long term filipina girl friend about advice on annulment , we truly love each other and want to be together in the UK , however she is seperated from her husband who she married about 12 years ago , we think we have 3 counts for annulment, one is he was unable to physically consumate the marriage , two he threatened and  intimidated her into the marriage after she told him she did not want to go through with it, three we think he was psychology incapacitated as he was a drunk and a drug addict and he aslo beat her , hold a gun to her head, and put a sword to her throat and is constantly threatening to kill her made her life an total misery . she has been seperated for several years, she now works in Hong Kong and is soon going to Canada , does anyone think we have a case for annulment as we both dont have mega bucks to spare , i have supported her financially for many years and have remained in contact via phone, letters and visiting several times , would it be an ideal for her to obtain a tourist visa first to come to the UK and then apply for annulment as we believe her husband may try and kill her , would she able to stay here under humanitarian grounds, would she be able after she came here under a tourist visa and be able to apply for another visa, please some one advice us as we truly want to be together and have chrildren one day maybe if she became pregnant with me would the UK immigration service grant her automatic right to come here , waiting for your helpfiul advice kind people
