my crush simply didn't keep any contact after rejection. I feel he really forgot his friend.
i believe this is normal...but i think you don't have to beat yourself up. there is no expiry timeline when someone should be over their ex and be okay again. it really depends how time and effort has been invested into the other person. for me, it has been 5years...but the regret is more towards why did i choose him to give my best to. because the heartbreak has made me bitter.
i've been in this situation for 7 years and to this day I still think about the times we had and everything bad that he did and he is the reason I am who I am today and I'm not thankful at all cause I'm bitter as hell like @FrenzyPants over here
