No you cannot control who other ppl invite. You need to find someone who is at the same maturity level as you. Someone who can handle the ex in your life. She will always be in your life and that you two get along. You need a strong confident women, not a young girl playing games still.
You can still find some beautiful mature women out there. The kinds who do not play games. That is what you're looking for. Someone to spend the rest of your life with.
