You don't really have the right to blame your ex-wife for your failed love life after you split. You know that, right? It's not like she walked around nailing posters to walls saying "don't go on a date with this guy!" Sometimes people fall out of love, that's just natural. It doesn't feel like you really loved her when you say "fuck you Alex".
Start working on being less bitter and maybe you'll go out on more dates. Good luck.
