It's a tough choice, to decide between being whole or having a relationship. There's no one answer. You will have to do what is best for you and your situation.
The dysphoria won't go away. Left untreated, it would have gotten worse. Since you have started treating it, I think that stopping treatment will make it much worse. Carly's advice is sound.
If you are an A/B cup already, you can probably forget about wearing T-shirts in male mode. I am probably only an AA at this point, and I am realizing that already I can't wear T-shirts any more until I transition socially. There's no going back without surgery, and based on your comments, I would think you would really regret that.
If you try to put this genie back in the bottle, how good a husband and father can you be if you are not whole?
As I said in another post today, I get the fear. I basically had to jump without a parachute, without knowing if there would be someone to catch me. I still shake my head in amazement that I did it. I didn't think I had it in me. But I did it because the alternative was unbearable.
You can, too.
