Sounds to me like you have a really good handle on what's up with you and your m. It's good that you realize that your insecurities are leading you to act in ways that aren't strengthening what you have. I can relate...I know what it's like to really feel as though you NEED some feedback/affection/whatever from h. Problem is, of course, that that clingy, needy persona just drives them away, right?
So...You've read DB or DR, right?
Do you have any specific (action oriented) goals?
How about 2 or 3 180s?
I'd like to recommend the book "men are from mars" to you if you haven't already read it.
My 2 cents? You seem to have a TERRIFIC understanding of what works and what doesn't. The key for you (you know this) will be to push thru some of your scary times and DO WHAT WORKS even when you want to cling or ask for reassurance or panic. If you build up a bunch of those times...you'll find it gets easier and easier.
Congratulations on facing your issues head on!
