What should you do if you like your best friends brother?

To like your boyfriend's brother can be really stressful. Especially when you see them all the time. But, what if you like some things about your boyfriend, but other things about his brother? It's hard, I know. Really hard. Personally, I think you should give you and your boyfriend a chance, see how it goes, and if things just aren't feeling that great for you, then maybe you should decide to end it. It would make liking his brother that little more easy to deal with, and you could get some stress off of your shoulders.
