I need to talk to you more to feel totally comfortable
So I have been chatting with this girl for a couple of days and we have similar interests. I asked her if she would be interested in going out for drinks/dinner. She said "well yes I would, but I need to talk to you some more to feel totally comfortable" From what she said the last time she went out with a guy he ended up following her to her house and tried to break in. Anyway I told her i understood and we have been chatting for a couple of more days. My problem is, how long do I wait before asking her out to dinner and making it a date? DO I let her imitate it or do I just wait a couple of week sand bring it up again?
