Get him to talk to me again?

Look to him you are a stalker, the fact that you send 50 text!!! WOW stop now and save grace, if you keep up in the same approach he will not speak to you in a long time. Suck up you pride and stop with the excuse of "his out of character" on the phone call..... please. Call him or better yet go to his place and talk to him if not interested move on write a letter and mail it with no return address so he just doesn't throw it away write how you feel say your peace and leave it alone. Let this cool down for awhile i know that's not what you want to hear but please sweetie if you both invested 9 months he is not over this just need some time and he will come around but be prepared for both good or bad. GOOD LUCK!!
