My ex cheated on me

I was in a relationship for 4 years and was shocked to hear that my fiance has cheated on me with an older woman. He confessed to me. I was so heart broken cz he is my first love and I trusted him so much. We kind of stopped contacting each other but we were checking on each other on and off. We were in a long distance relationship and we were in two different countries. we were planning to settle down in the same country and this problem just ruined everything. After I returned to my country ( two months after his confession), he has started chatting to a 19 year old air hostess and she put a big show on facebook so I knew he was up to mischief. I asked the girl and she said they ve known each other fr 3 weeks and she loves him and he says he loves her too.I was feeling terrible cz his parents and family knew about us. So I informed his family. They were in utter disbelief.However he returned here about 3 weeks ago and I contacted him out of the blue. He never answered my call , instead he texted my sister telling me not to contact him. I havent talked to him for 3 weeks since that and he has been chasing me to get my details to deposit the money. I have already sent the details through my sister but now he says he wants to talk to me to know the exact amount . He has unblocked me on whatsapp recently cz I cut all the ways he could contact me ( deactivated my fb, no viber and I switched off my whatsapp status too ) . I really miss him so much and I really dont want to lose him. But at the same time Im so upset cz he didnt even want to talk about our relationship before jumping in to another relationship. Please advise me on this. I feel so terrible cz he has been a huge part of my life and my family and I miss him terribly.

Truth you are grieving him and will be for a while because he was a big part of your life. But he has let go of you a long time ago when he cheated. when you gave him another chance he probably lost respect for you, and or/ knew things were going not be the same. Once trust is broken it is very hard if not impossible to build again. I would allow yourself some time to get stronger and get over the loss of him and this relationship. Never go backways
