Rebshidduch, if your friendship with this girl resulted in your doing things that you shouldn’t have, then you probably should drop the friendship. Not because she is not a good person, but because the friendship is not good for you. Just like this guy might be a very good person, but it’s not a good relationship for you.
I would advise you to reread DaMoshe’s post and take it seriously – all of it. What you need right now is not a shidduch. In fact the fact that you are so desperate for one is a bad sign. I have found in my experience that when a girl is desperate to get married (or is too into boys), it means that she has issues that she needs to deal with before she should be considering marriage. I have also found that those girls usually end up divorced – sometimes more than once.
