I'm in love with someone who doesn't love me back
So does this mean it is the beginning of the end?
No, I want to change myself so he will love me.
If he can't accept you the way you are, you should walk away. There's someone out there who will love you for who you are, not what they want you to be.
I just want to make a change so he loves me.
That is the saddest part about it is that you are willing to change yourself. I think you should find someone that will love you for you and do not try to mold yourself into someone you know you aren't.
