Married for 12 Years with 2 Kids, Wife Cheated Repeatedly. How to Decrease Anxiety and Rebuild Trust?

hi anuji. I have been married for last 12 years with 2 kids of 10 years. in March I came to know that my wife is repeatedly on call with one person. after checking call logs came to know that she was in touch with the person from last 8 months. initially she denied and informed that she is talking with her female friend but on Truecaller male name was displayed. when I confronted 2-3 times she agreed she was speaking with male person but he is outside town for training purpose. when I checked the persons records I came to know that dates provided by my wife were incorrect. I went to marriage counseling and after repeated confortation she agreed she has committed mistake and asked for forgivenes and requested one chance. after 2 months I came to know that she has lent money without my knowledge to 2 people whom we had agreed that she would not speak 7-8 years back but now came to know she was in contact and has lent money and jewellery without my knowledge. people are refusing to return. these incidents have happened 4-5 months back and wife has moved on but it's difficult for me to trust her even after 5-6 sessions of marriage counseling. currently we are enjoying healthy married life but back of mind it's very difficult to trust my wife and I face anxiety and depression issue whenever such thoughts crop in my mind. I am been in marriage for children well-being and overall family well-being. I have already informed her parents and given ultimatum that if such things repeats then there wouldn't be any chance of recourse. last six months have been worse due to this issue. I want to know how to decrease anxiety and fear of such issue cropping in my life as it's getting difficult to trust.
