Boyfriend help

in July 2012 I left my husband. We had one son together, but my x is making my life hell. I feel like I can get on with my life because he is watching evey move I make. I want to date again but can't seem to fine one that want to be with me after I tell them I have a son and what my x is doing to stress me out. How can I get pass that and move on with my life and find that guy? Anyone please help.
