Have you met his family?
You have been through the most appalling trauma yet you have survived and are able to look forward to the future. That is an great achievement and you should be proud of yourself, not ashamed.
I can understand you not having a great opinion of men but you mustn't assume that most men will think you are 'not good enough'.
You don't need a man in your life at all, but any man you do consider having a serious relationship must be 'good enough' for you. You absolutely must be able to share your history with him or you will be forever frightened of him finding out.
Also our past colours our future and emotional trauma can affect the way we react to situations. Your man might, at some point, introduce you to a male friend or relative who triggers alarm bells with you, probably for no reason. If you have children you will worry more about some things than most other mothers, not necessarily a bad thing, but you might need your husband's support to gain perspective, a balance.
If you don't feel you can tell your boyfriend about your past he really is not the man for you.
