Most Helpful Guy
I'm really sorry to hear that. All I can say is that it doesn't sound like you two were doing that well before this so you need to understand what was wrong before this happened. If he won't respond, give it some time and try to evaluate your own behavior. Is there any merit to you being impatient?
Also, you need to understand that you can only change yourself. No matter what conclusion you come to. Whether you had been at fault or he's just an unappreciative jerk, the only person you can change is YOU and hope that he is the kind of guy to respect that and follow suit.
I sincerely hope you get things worked out :)0
