Can't say that I've read Erin Pavlina's blog much, but today I read this:
How To Become a Vibrational Match for Your Desire
and I think it applies to your situation. You say you are attracting men that are more suitable to you, which is great. But part of that suitability is someone that doesn't reject you, but instead accepts you. So who you are attracting isn't exactly spot on yet. Which, if you are willing to give the LOA concept a try, means there's still something in your thought pattern that is getting in the way.
I'm gonna take a great big guess here, but the very idea that love=pain is a thought/belief pattern, and according to LOA, if you think that, then that's what your reality becomes. Erin expains all this and what to do about it very well.
And just for the record, I almost cannot believe that I am talking up LOA! But I've seen some evidence of it recently, so I'm willing to give it a shot.
Hope this, well really Erin, helps.
