I have a little different point of view. The question is not, "Do you love your wife," but "Do you love YOURSELF". If you do, why would you plan to never give yourself the gift of a committed marriage with someone who loves and supports you, but instead decide to set yourself up for a life of revolving 5-year relationships based on a dopamine high?
You have read that an affair is (like) an addiction. A student of psychology I trust (Silvan Tomkins) wrote that people who feel good are not turned on by addictive substances. The problem is not that the addictive person or substance "makes" you feel good, the problem is "Why don't you feel good already, as you, in the life you have created for yourself?" If you don't feel good in your life, the only person that can change that is you.
And, no, co-dependence is not the solution. That just means trying to "make" the other person feel good, with the unspoken demand that they "make" you feel good in return. Therapy is a place where you can explore what is inside you that keeps you from feeling good. What were your childhood experiences? What did you conclude about life from those experiences, and what did you decide to do to cope with life? One reason people may feel scared and think therapy is not working, especially in the beginning but also later on, is that they have an inner sense that if they go inside they will experience the PAIN they have been trying to protect themselves for many years.
6 weeks is nothing for therapy, and 2 months is nothing for getting out of the fog. I would go with the usual SI suggestion to not make final decisions for 6 months, and to not make decisions for your partner. If she wants to end the marriage, that's for her to decide. You don't have the right to "help" her by leaving before she has asked you to go. If you choose to leave for yourself, that is your right, but be clear that it is about you, not her.
You have a lot of work to do, but you can do it. You're worth the time and effort, and so is your wife. Do remember that that effort does not include pretending and hiding your feelings. And your wife can leave at any time. Have you asked her what she wants? Your posts have been all about what you're thinking and feeling, but I don't have a clear sense of what she is thinking and feeling.
You may decide to leave this marriage in the end, but your "I don't knows" don't give me the sense that you know that is what you want to do at this point. Whether you decide to go or stay, don't give up on yourself. keep digging until you can clarify both the good and bad in yourself, decide what you want in life, and choose to go after that with integrity.
