Confused wife: Can't move forward without forgiveness from emotionally distant husband

Hello, I am a 42 year old woman with a 14 year old boy and a 12 year old girl. Ours was an arranged marriage. I got married at age 23 and my husband is just 2 years older to me. Right from the beginning my husband is great at cooking, household chores etc but never expresses romance openly. I was always a emotional woman who slowly turned to him and stopped expressing my needs well. So far out marriage was great cos I avoided confrontations and arguments. Only thing was he was always a critical person and I am emotional girl . Since I cld not express myself clearly as he never heard me, my communication with him sounded nagging, comparing and complaining. In 2011, he cheated on me and I learnt on his affair. I did not know how to process this phase so immediately forgave him within 2-3 days and even ended up being pregnant with my daughter. However he never used to speak on his past affair not were my feelings resolved. Whenever he would speak rudely or yelled at kids or me for little things, the past trauma would trigger and I would openly remind him of his grave mistake. This went on and he would get agitated and keep quiet. One day he did tell me that lifelong he needs to live with this past of me reminding him. But he has never understood the trauma I have gone through. I have just repressed it all along. Cut short 2024- there is lots of resentment with us. In 2022, I saw messages that he exchanged with another lady colleague on romantic songs , good morning messages and they would casually meet for lunch etc . This time I flew in rage and assumed he has cheated on me again. Told him first time I was a fool who didn't notice things right under my nose and now this is the latest. We had a big fight. I reminded him of his dirty past. At first he looked shocked from these allegations and told me he will clarify everything later. But next day in 2022 , when I asked him, he appeared to be a changed man and sounded more confident that he didn't do anything wrong. I pestered him to take me to office, we went to his office I met this lady and politely told her to stop sending good morning messages to my husband. I indirectly told her I have trust issues because of a past but did not elaborate. My husband who had taken me to the office , later was annoyed because apparently the woman colleague was annoyed about me coming to office and also mentioned about my trust issues. At this point this great husband spilt out to her that he had cheated on me. I never ever disclosed anything to her. Later he messaged me saying he was very annoyed and upset that I disclosed the dirty past to his colleague and if anything happens to his job he will never forgive me. I did tell him I never disclosed but he did not belive me. From 2022 until now we are almost in a silent divorce phase. We sleep in different bedroom and only communicate basic stuff on milk, curd , veggies etc He had never connected to me emotionally and would always get annoyed when I wld cry or show my frustrations. Now after all this he has literally cut me off emotionally. In this period from 2022-till now I did try to get back to normal but his vibes are very negative and disconnected. So even I too started distancing myself. During 2022, after the incident he had mentioned on how it is important to work, ve independent and how he favours open relationships ( non sexually). I was always working but earned lesser and used to depend on him a lot. Now I have changed in these 2 years, I have a better job and am not at all dependent on him emotionally, physically or mentally. Infact I pitch in to our household expenses.Our lives are totally disconnected and we there just for the kids. He cooks for all of us, I take care of remaining chores and help them in their studies . We don't attend family events and this has left many guessing on our status. I have lot of unresolved emotions and since he cannot process my emotions or least interested to hear me out I don't know when I will explode. I am just repressing my feelings and keeping a happy cheerful face for the family and kids. We even went for a vacation for kids sake where we just interacted with kids. Kids know things are not allright and pray for us together. I know this isn't healthy for me and I will invite psychosomatic issues in life later on. I am still attached to him and maybe once he expresses a sorry or a remorse and have a hope we can fall back in love again. Why can he never understand that emotional trauma that I have gone through Inspite of being loyal to him always. For once if he just uses kind words and apologises I will forever love him and forget everything.
