To write or not to write...

If he wasn't listening back then he won't listen now. Why write when you can show him through your gestures how you feel. Too much talking has this hidden message that it's not working and some men feel if I have to talk it to death then it's not going to work and I should let her go and move on to new pastures.

Try a more demonstrative approach, like inviting him out on a fun mini date to see if the spark is still aflame and this should get the ball rolling again and those little connections you're creating can open him up to think about you and think about being with you.

Just my suggestion, I definitely don't suggest you continue to talk about the same thing over and over again, it's a form of nagging and it doesn't work, try a new approach instead.
