I agree with the expert that you should find a therapist in your area. The confusion you describe as she said can be addressed so that you don't feel so alone and they will help you make an informed decision. What you describe as confusion can simply be a host of emotions coming at you regarding several concerns, - your marriage, your job etc.
Don't fear therapy. As far as your relationship, I don't think you are being unfair regarding the finances. You just want an equal partnership. Lots of career women want this same thing. Sometimes when women feel they are doing more, sharing more, or providing more they begin to feel resentful. This imbalance causes feelings of resentment. This sounds like part of your problem.
There may be hope for you as a couple but that is really your decision. Sex should not be the best part of a relationship. You should have different deeper benefits such as trust, honesty, integrity, companionship, etc. If these things are lacking then you need to decide if it is worth saving and get professional help. If you know in your heart it isn't then you have no choice but to voice these concerns to your partner and take it from there.
This decision is not for either of your family's benefits. You need to have a discussion like none you have had before. Figure out where you want this relationship to be in the future. If you don't see one, tell him as much
