Maybe is his first love which is hard to let go. Be single for a period of time until you let go. I feel you when my first love dump me. Now I found a better gf.

On the other hand do more charity, any amount would do. To anything or anyone (pasar malam or charity organisation). But also use your heart to feel is it worth do donate also la. Dun simply give those ppl that you obviously know they're con man. I found out that doing some charity can give you inner peace.

Sorry Im a half free thinker.
