My wife is an alcohalic and ive had to forgive the worst things. ?

her confession was in June and we are trying to move forward. She has been sober since and we are doing better than ever in alot of ways but I still hurt. i want to believe that she was meeting this guy cause he was buying her drinks for her but i jus want to feel better. We have a 6 and a 2 yr. old Will this heartache and mistrust go away or should i start again?
