So confused with these boys?

Hi there ( btw I am on my phone so there may be misspellings..) okay so there is this buy I like and he likes me still I am pretty sure so the past couple of days we have been flirting and then two days ago we both kind of said that we are going out but it isent really clear but there is this girl and she is pretty and nice but I think my boyfriend likes her a little ( and my boyfriends bro likes her and so does his friend but it has been made clear that she does not like them in that way so I like this we are freinds but I feel like she is taking my crush a way. Now this sounds really lame but I kind of like my boyfriends brother cause he is really funny and fun to be around but I am pretty sure he does not like me like that I think. I am so confused and hurt what should I do? Thank you all!
