What's wrong with just being friends? Nothing. Do the positives of being with her outweigh the other things you think about her? The harsh reality is that relationships never get "easy". There is no book of right and wrong, no checklist to follow, no green light that comes on to tell us that "this" is the right person. With experience though, you will develop a feeling for what's working for you and what isn't. Try being the best friend you can to her. With 8 siblings, I bet she needs it and it will give you both a chance to get to know each other better without the pressure of trying to make something happen. This can be a win-win scenario no matter what you two decide to do, keep a positive attitude about it the best you can.
