What I would suggest is to speak to a male scholar in regards to your question and deep concerns. What I can say is yes attraction is very important and beauty lies in the eyes of the beholder. This physical beauty will fade away soon. What will remain is the soul beauty and being soul mates in marriage. You definitely need to go for therapy and also couple counselling. The influence of online world is a disease that has destroyed families and we need to be weary of the consequences in a marriage relationship. I would recommend that you speak to a therapist who can help you heal and also a spiritual guide to help you with protecting your imaan and your marriage. There needs to be empathy in a marriage relationship and imagine if you put your shoes in her place. Just think about it.
