I did this exact thing with my ex...as I went through the roller coaster of emotions, I sent him messages saying I was fine to desperate messages saying I needed him in my life....he must have been really confused because my messages went from A to Z as I went through the grieving process..and still do....It's hard to say what you ex is thinking, but if you really feel the way that you did in your last message, then I would leave it at that...going back and forth is going to be hard/confusing for you both....and he needs time to think about what he wants...he won't get this opportunity if he is getting mixed messages from you...trust me..I WISH I could have left well enough alone...but I panicked and was sending him a ton of messages every day...didn't realize how many until I just got my cell bill

....I may have pushed him away..but in the end, I am ok with this because I would not want someone who would just suddenly shut me out and not return calls/messages...it is cruel...Give your guy time to think..the time will likely do you some good as well....
