Insecurity

I got married to my wife 2 months ago. But at times she talks to her ex. The first time she talked in front of me, I thought it was her brother, and I could hear him making her laugh. When I talked abt this to her she said if it was abt cheating on you I would t call him in front of you. She said we have had veen together for 5 years, we raised children together, at this point he feels like he is my brother and we are still friends. And if it was like that I wouldn not be here with you. But I am with you, at your house.

Before she told me in the past because that her ex couldn't give her financial support, he had a big house, but his job wouldn't gave him a raise so she was financially insecure abt her future, and he was getting old as well as he was in his 50s and she would even fear that she would die and she would be left with nothing and also she was getting less sexually attracted towards him because he was using testosterone supplementation for having an erection. I had a rough discussion and asked her to leave me but I gave her a chance and she agreed that she would stop talking to him. But she didn't, at another time after thih happened I was in my apartment pool, I called her her phone was in waiting. When I got back I asked who she was talking to she denied telling no one. But after asking for more than 10 times she told me it was her ex. And she did admitted at that point she said by herself that yes this is a form of emotional cheating. In addition to this she also has a rich guy friend from the past she is known him for 15 years, once when we had a fight, she asked help from him and he was on the speaker and he said in exhange of helping her he would want some sex with her. I grabbed the phone and cursed him wi the most worse things. But even after thst event she till talks to her secretly. I dont know why does does that. She is not working and remains at home all the time, and whenever I come back home and I am suspicious of not replying to my texts like after 2 hours and sometimes 3 hours when I am at my work and then suddenly when its time for me to come back home, She starts texting and replying me instantly. When I come back home and ask her who you were talking to she says that I am insecure and most of the time beats me as well for doubting on her. I dont know I want to be with this woman but her this kind of repeatitive beha vior stresses me l the time. I cant focus properly on my work, job and things to do. How can I live constantly stressed about this thing because I have another life where I have to work, earn and focus more on my career.
