Re:i wish i could send t_b: Don't feel ashamed. Like the others I could have written this.... your letter went straight to my heart. You are not alone... Sadly there are other people other than your ex who have treated their partners in the same way... Hold you head high and don't beat yourself up. You are entitled to have strong feelings and articulate them... The only advice I have (and it is based on my experience only) is that you will end up getting hurt as you say either through no response or a selfish hurtful response.
Face it, there are enough people on this site who are committed to marriage that there must be lots of good ones still out there.
Stay strong.
