help me!

so I've been dating this guy for a long time and all of a sudden it's like he lost interest in me. he never talks to me and seems to just blow off everything I say. last night this guy snapchatted me saying he loved me so much. he showed me so much attention but like he's just not my type (if you get what I'm saying) I don't mean to be mean. but I don't know what to do. I told my boyfriend and it's like he didn't even care. I need help from some girls!! I don't have a girl friend to help me so maybe you guys can?
