So how I become semi... Part 1 CUCK

I am 43 married to 42f for 16 yrs now. It all started when she caught me cheating on her with a Hooker. I was married for 12 yrs to her then when she caught me red handed. she asked me for divorce that time only and I literally pleaded her not to leave me as by then we already had 2 kids and if my relatives would have came to know the real reason, it would have been very embarrassing to me for the rest of my life... She gave me 2 choice... either she will leave me or she will take revenge by fucking her EX and i had no option then than to say yes .. I thought time will pass and she will not go to her EX for real. I honestly thought she is just punishing me or hurting me by taking her EX name but after few weeks she literally ask me to drop her to EX place and to pick her up when she calls me back. I HAD NO OPTION
