Would you say him giving me his new number is a good sign he wants the friendship back too?
It looks as if he is at least open to communication from you, or he wouldn't have given his number. But that might be it, izzy.
It sounds to me like you are hoping that things will be different this time, but I recommend proceeding with caution. You are already walking on eggshells, before you've even called him (worried that he's angry and that calling him will make it worse). I don't think that is a good way to begin a satisfying friendship, do you?
Is he the kind of friend you want and need in your life? Does he have what it takes to treat you respectfully and in a caring way? Are you ready for the work it will take
from you to make sure your needs are taken into account?
Only you know the answers to these questions. There is no rush. What do you think about giving yourself a few days to ponder your next step?
Let us know how things are going.
