The Taking personally thing is because you hold him in your heart, and where there is love there is always forgiveness. You forgive him! That’s my take on that! Because I do the same, but although you’re right the other guy did take advantage with an understanding of what’s happened to you, he really is only in your head and not your heart!
Heartbreak and disappointment has to be the saddest thing really! With heartbreak lies, sadness, confusions, loss of hopes and dreams, love, excitement, encouragement and all the rest of it and so when all of that is removed, a part of you gets removed with it. That my friend is why you should guard your heart, and give it to the one who deserves it. Some people are like vulchers out there.
You won’t always be sad I promise that. You may look back and reflect but that will be fleeting and will pass with a sigh of relief
