The heart wants what it wants

"I felt like I know him And I know his heart, and I know what He wouldn't do to hurt me But I didn't realize that I feeling so confident And feeling so great about myself And then it just be completely shattered By one thing. By something so stupid But then he'd make me feel crazy Make me feel like it's my fault I was in pain" sounds awfully familiar and something I can totally relate to in the past..
