I just feel as part of being close with someone they should know I've had some problems, and in my experience most people would write me off at that point as there are plenty of others out there who are free and clear.
I think you should reconsider that position. I don't know anyone who lacks baggage. It mostly varies by type and color. That doesn't mean you shouldn't work on your issues. But, really, everyone has crap in their life of some sort, and they still need people. Of course, alone time can have its benefits, if you prefer that.
