I can't help but wonder why, if she is the "love of your life" you are you worried? That part is a little confusing. Try listening to Anxiety Free, since it sounds as if your biggest block is fear. You are making yourself miserable.
And a blanket statement such as, ..."I do know they have a way of manipulating a situation so it ends up being the guy's fault", is a pretty limiting belief. If you think that is true, I wonder how it's possible to have a good relationship with anyone. Be careful of the limitations you impose on yourself.
