It sounds like you have a lot of issues in your life to work on. Would it be helpful to have the support of a therapist as you work on them? Or can you do it without a T's support, on your own, or with the support of friends and family? For example, now that you know your marriage sucks, do you know what you will do it about it? Could a therapist help you explore that, make a decision, and take action? For the verbal abuse, could a T help you practice techniques of setting boundaries and not taking the abuse anymore? For #5, could T offer support as you seek to add people to your life who are healthy and compassionate?

I think there is so much to work on there. But it is up to you to decide if T can help you with all those issues or not. I also worry about #4 and how you say you push people away. Is your contemplating ending therapy a way of pushing your T away and repeating an old pattern?

I think you have a lot here to discuss with your T, if you still want to work with him.
