Yesterday evening i was opened my dog cage for it to come out and poo, but instead d dog started playing around so i went and i lifted it by d neck and i was trying to drag it back to it's cage, while doing dis d dog sratched my hand wit its teeth....pls hope dat wont have any side effect like rabies?

Please am in a serious state of confusion my fiancee and i have been in courtship for 4years now and she saw me through school wit her 10k monthly salary from workn wit a filling station she did alot for me and my siblings and jst few months to when i wanted to resume for my final year in school she lost her job and things became hard for us and just three days i saw a camera inside one of her bags which she actually showed me before that it belonged to a man that has been asking her out since last year which i am aware of, when she first showed me dis camera last year she said i should pls try and see if i can repair it but i didn't have d chance to do that which made her dump d camera inside one of her bags, when i saw dis camera 3days ago i opened it and decided to check wat was on the memory stick and to my suprise i saw different naked pictures of different ladies naked but with d picture of d same man althrough and dis memory stick contains clips of wen dis man was having sex wit dis different girls who didn't even knw hw was recording dem and his own face was also showing clearly wit even many naked pictures of himself. And dis camera d man usually set d moment dis girls knock and after dat he quickly rushes to the door to open all dis i saw inside d numerous clips on the memory stick @ different times n while i was wonder hw my fiancee got dis, i saw her own clip too but i didn't see her pictures and wen i checked d date on d video it was august last year. When i showed it to my fiancee she started crying saying she has cheated on me and when i asked wat led her to dis she told me wen we were looking for the means of paying my school fees in my final year dat was wen she agreeed to d man request bcoz all hope was lost and she said d man didn't later give her d money bcoz i remember it was her mother who later collected daily contribution money which she gave to us to pay for my school fees when we had no alternative am sure of dis because i was there when her mother collected d money. And she said she didn't know dat d man recorded their sex, when i asked her how she got d camera she said on d day d man finished havn sex wit her she noticed d camera and askd d man y d camera was @ dat position and she said the man said d camera wasn't working and dat it's wasn't useful anymore dat she should leave it and she said while she wanted to leave d place she took the camera witout d man knowing and after some weeks d man called her to ask about d camera and she said she told him she didn't take it since he said it wasn't workn and she said d man said ok maybe he misplaced it and since den d man neva asked abt it again. Please people am confused i dnt knw wat to do if i should leave her or continue wit her, she said it was her first time of ever doing such and she had wanted to tell me but she was scared of loosing me dat she did dat bcoz she didn't want all her effort all dis years over my education to go in vain. Please people i need your help
