With the ups and downs of relationships, getting disappointed, lied to, getting really hurt, maybe even divorced. Can you still let someone love you, can you even believe it if someone says they really do want to be with you (other than sexually)? Where are you feeling in all of this? If you can’t identify with all those emotions/ feelings can you write about someone who is?
Write about falling in love, again, after you’ve been left by someone else who made you believe in happy ever afters.
