OronD I think is right. You are just hurting your wife and its wrong, because you've not only had just one but a few affairs meaning you dont truly love her nor have a bit of respect for her.
You need to tell you wife you are going to go away for a week and think everything through. You cant contact any of your lovers or wife. You need to figure out who you are before you can be with someone. You cant love both women, you may love what you get from your lover and love what your wife does for you(washing clothes, cooking dinner, etc) but you dont love them. Figure out if you can love someone and be true to them then figure out if you can love your wife and be mature by not cheating on her.
Then go back home and tell your wife why and what you've learned.
