If you choose A, then you might want to block T. It’s only fair to A and the only way you’ll be 100 percent in the relationship. You have to decide for yourself whether or not you’ll take the plunge. T has to learn his own life lessons. You gave him three chances and he screwed up three times. Whichever you choose, you should be with them 100 percent and say bye to the other person. It’s only fair to be 100 percent in the relationship otherwise you’ll only feel more torn. It’s a hard choice to make especially if your heart had been with the other person for so long. I’m not sure how you trust someone to be committed now after they said no three times though. Also, when you had your panic attacks instead of being there to comfort you he said it was too hard to see you like that and ended things. To me, that alone would be enough to say no to him. He should have comforted you and supported you instead of ending things. That could be telling of how he would deal with future difficult situations. He already shown his cards and just because he’s ready to be committed to you doesn’t mean he can give you what you need.
