My ex broke up with me 3 months ago. We were together for 3 years. I was her first female relationship. She is "friends" of about 3 months with another female. For the last 2 months, I have sent texts and emails to my ex explaining my feelings. She only responded once. After we talked for a while, she stopped responding all together- although it was a very sweet and heartfelt communication on both of our parts. Since then she changed her phone number. Will she ever come back?
