I liked her, but her past interfered?

I have a small dilemma here. I actually found out more about this girl before I even met her in person and before she even knew I existed.

Through various sources, initially, I found out that she was a single mother and that she she screwed 3 people whom of which I knew personally, one being a close buddy of mine. Some months later, ironically, that very same close buddy and I ran into her at a club. He then introduced me to her. From that moment on, apparently, I caught her eye considerably. She is a very cute woman and is very nice so we danced and we flirted with each other here and there.

Not too long after, maybe a few weeks, she came out and told me she wanted to get to know me better. Quickly, in response, I told her that her responsibilities as a mother, at least for me, would interfere with my need to have a full time relationship. I didn't however, tell her about those other three reasons (the men that she slept with). A few weeks after this, I think she must have let my response slip her mind. This was probably because every time I would see her at the club, we would dance and I would hold her close to me and treat her like gold. Again, she hinted at a relationship, but again I denied it.

The reason why I pulled forward with the affection was because I wanted to see if my heart would allow me to overlook her serious imperfections. That being said, every time I looked into her eyes or thought about her I couldn't help but think how her child would get in the middle of the relationship. Not to mention the stories those guys told me of how they made their way with her. I mean, with things going through my mind like that I knew right away that those ideas alone would cause the relationship to fall apart considerably. I believe my decision saved her some heartache. Don't get me wrong, I ended up falling for her, but at the same time, I knew her faults would cause that fall to wither away.

Ever since then, she's been making me feel pretty terrible by posting stuff online on how, time patience and the very will of two people who truly want to be together is the recipe to a great relationship and how nothing should get in the way of that.

Am I wrong for making this decision? It just seems that every woman who proposes an interest in me has some sort of significant defect that is highly unacceptable. Being a single mother and the sloppy 3rd and 4ths of my friends at the top of the list. And the worst of the worst being women who have criminal records and even one who had a pretty serious std. When will I ever catch a break? I feel like I'll never find someone lol.
