Hi Katied...
Welcome to the forum!
Women are at a slight statistical disadvantage when it comes to finding an addiction free partner... unless they like women, that is.
There are also all kinds of theories about how children of addicts are attracted to addicts. I"m not sure I buy all that, and I'm not a psychiatrist, so I won't expound.
If you are not attending al-anon, that might be a good place to go for insight. It's so much easier to recognize patterns in other people than in ourselves. I also have friends that seem to get a lot out of individual counseling.
You are not alone. If you read some of the posts on the nar-anon page, you will see that there are lots of gals out there who keep getting on the merry-go-round. Why? I'm sure that's a pretty individual thing.
Keep on posting!
