My love life

I like this boy but im not sure if he likes me back We used to go together then we broke up because he lost intrest or whatever he still acts like he likes me But I cant tell he my brothers friend so hes always over my house ithink ilove him I havent felt this way about a boy before Can you help me?

act cool and calm, try not show any interest in him, and he might start to feel a little rejected and then start liking you again... look nice everytime he comes over your place, (but dont over do it)
