[Sean Mac]

Back in january i stupidly got talking to a woman via facebook,she told me about her life,about being unhappy with her marriage & stupidly i developed feelings for her tho we are both married,i met her once and we just talked,then another guy appeared on her fb account and started to blackmail me,saying he would bring all messages i had sent her to my wife if i didnt pay him £1400.i asked her about this and she became nasty and also issued threats to me,2 weeks ago her husband came to my door saying he was getting divorced and gave my wife copies of all messages i had sent to her & that i was being named as 3rd party in divorce. I swear i never slept with this woman but my wifes heart is now broken and im feeling so depressed,i hate myself,i was sent death threats by this other guy she was seeing on mt mobile but i deleted them after i hadnt heard from them for months thinking they were leaving me alone,id told them id lost my job and couldnt afford to pay,i told mt wife id never met her which is a lie and fear what will happen if she finds out i did even though i was only talking,will i end up in court over their divorce? will i have to pay legal fees?my family are torn apart over these peaople and im so sorry,ive left facebook now as i can never trust anyone again,ive never cheated on my wife b4 and i love her so much but ive hurt her now and wish i was dead,please advise me,i dont want to go to the police and have this blown up in the loacal papers,i live in n.ireland so uk law applies,please tell me what u think
