BNL - maybe take a step back from the situation; you don't need to make a decision NOW. Continue seeing your T as much as possible and first and foremost work through your feelings, your needs, your wants.
Then consider your relationship, and if all the above are met. Consider if changes can be made to make things better. Give yourself as much time as you need to consider every possible angle and only then contemplate making a decision. By then it will be crystal clear.
Please look after yourself, and promise to at least call your T if those thoughts get too much. And think of your lovely kids; and your PC family who love you dearly!
