I think your doing the right thing for the moment. Not speaking with him is good for now. What has happened to you has obviously been very traumatic and your recovery will take time. Why the hell did he break up with you only to regret it immediately after??? You have absolutely every reason to be angry with him after ruining your wedding. Did he get cold feet at the prospect of tying the knot? I don't know the full story so it's difficult to give more definitive advice. Sometimes people make mistakes and yes he could well have made a massive mistake for which he is now extremely sorry. Question is whether you are prepared to forgive him and consider reuniting or if this break up has extinguished the love completely. Obviously you have lost your trust of him and regaining that could take a long time. If you feel in your heart that you do not want to get back together with him then continue with no contact whatsoever as your course of action but if you feel that it is just anger and deep inside you do still love him then have a chat and see what he has to say. I must say that 30-50 text messages and 20 missed calls is somewhat obsessional and that in itself is a bit of a worry. Chin up. I am sure things will work out the way they are meant to be.
