Been In a good/bad relationship for 2 years. Brothers Bestfriend just told me he's in love with me. What do I do?!
Short version. Run off together and elope.
You need to tell him how you feel about what he told you. If you are also in love with him, you need to let him know that you are also in love with him and talk over what your expectations are.
head for the hills
I guess if you're saying "good/bad relationship", maybe there is no future as yet on your part. One must be happy in life.
