Can someone give me honest advice?

I have been in a relationship like that before. It really depends on if it doesn't workout how well you both take it... for us it made our friendship grow, i think of him as a brother and he thinks of me as a sister now. it's nice to know that i can go to someone that knows me really well... now we are both happily with someone else and the 4 of us are great friends... so all in all it depends on how it ends. I say take that chance tho because you never know unless you try. i hope this helps. best of luck to you. and i hope it works out for the both of you.
