Adelgal, you are
not "damaged goods" any more than every human being on the face of the earth is - we've all sinned and fallen short of the glory of God, and we are all saved by grace alone. And this is something a lot of people don't realize, but I'm pretty sure most families have some level of dysfunction in them. I grew up in a Christian home, went to church all my life, and even went to a Christian school and a Christian college, but that didn't cover the fact that my upbringing left me with huge scars I had to deal with later, or the fact that my dad left my mom while I was in college.
Now, if this guy you dated was really leading you on, dating you with no intention of ever marrying you, that was a huge error on his part and I hope he will one day realize what a terrible thing that was for him to do. On the other hand, for myself, I don't think at 19 (the age I started dating) I would have been able to date, say, somebody who was divorced or widowed, simply because those life experiences were so far beyond me that I would not have had the same level of maturity as somebody who had been through one of those situations. I think we all have different needs at different stages of our lives, and God can guide us to the right person for whatever stage we are in.
My cousin had a baby when she was 17. The guy she was with at the time was a drug addict (I don't know, maybe he still is) and unfaithful to her, and when he eventually asked her to marry him she said no. Now she's engaged to a guy who is a Christian - who has also made similar mistakes in his life but seems to be on the right path now - and who sounds like a really great guy. She had to wait a little longer than she wanted - her daughter is now 7, and she thought that while she had a kid no guy would ever consider marrying her - but she found the right guy at last and I'm so happy for her.
Some people out there are not worth dating, for one reason or another. And that doesn't necessarily apply only to those who are bad people. I'm sure there are some people out there who are perfectly nice good people, that are still not worth dating because you know from the beginning that it won't work out. Obviously you don't know whether you'll end up marrying a person when you just start dating them, but on the other hand, if you know in advance that you
wouldn't marry a person, it's foolish to go out with them.
Anyway, I'm rambling, but the point is, don't give up or lower your standards just because you dated one guy who was a jerk.
