I might be heading for divorce, any advice or guidance or ideas?

TLDR: My wife and I have grown apart and I feel very sad and bored in life. She doesn't show any ambition to change things even though I've tried to make things better. Considering divorce at this point. Marriage counseling to start next week.

​

My wife (F 33) and I (M 31) have been together since I was 15. We've been married for 7 years. She's all I've ever really known in a relationship. We've grown apart a lot since we've been married. We used to be happy as ever simply watching tv, reading a book, playing cards, etc. In the last couple years I've been depressed and not happy at all in my life. I started counseling and medication and while that has helped me feel a little better my life is still the same and I don't like it. Since about 2015 I've become much more physically active and have picked up several hobbies such as international travel, hiking multiple days in the wilderness, hiking mountains, biking, golfing, and many more. The hiking and traveling have been the hobbies that have stuck. All of my international trips have been with other people. Much of my hiking trips have been solo or with somebody else. I've invited her to come on a lot of these trips and she often declines. She's a very simple person who enjoys being at home with a book and watching baseball games. She's not in good shape and takes very little initiative to take care of her body. I've taken her on a few hiking trips here and there and have tried to get her involved but I don't feel she has put forth any effort. I don't expect her to completely change who she is and I feel bad asking her to show some initiative and ambition in life. She just seems so happy to be still where she is. I, on the other hand, have become a very adventurous person who does not like sitting around. I am always planning where to go next and what to do. We had a long conversation today about how we feel and what we both feel we need. It kind of just reinforced my feeling that I need to have some distance from her. We have agreed to start marriage counseling next week. I feel very held back by her as I don't like going on trips without her....I want her to be with me and she knows that. But she doesn't traveling much. I just want to be with someone who enjoys doing things with me and has some things in common with me. My wife and I hardly have anything in common nowadays and I really feel like I need to move on...without her. If you've read this far thanks for reading.
