All i can say to this is that i really wish my Ex was in the same position as what your boyfriend is in now. Its so good that he wants to change. and i would be hurt too if he wouldn’t let me in and see how he is changing and the progress that is he making.
So what is the next step, you just stop talking to him until he is ready to talk to you again? I think from what he has said to you already that he will recall the feelings he has for you, just don’t hang onto his every word, you will only hurt yourself in that process.
Hope you are ok and keeping safe in times like this xx
