If a boy likes you,he'll probably be flirting and waving constantly because he's trying to make a good first impression.
Sounds like he/she doesn't like your boyfriend or is afraid of him. Has your boyfriend ever mistreated the cat? If so, get rid of the boyfriend asap!
Apparentely if he is your BOYFRIEND!!!
She doesn't have a boyfriend.
She currently does not have a boyfriend.
Dump your boyfriend
A Boyfriend is like Boyfriend & Girlfriend. A boy friend is a friend that happens to be a boy.
It is always your privilege to like somebody you want to like, but it doesn't mean your friend can control you to get a boyfriend... Does she have a boyfriend herself???
find another boyfriend who does.
be honest with your boyfriend
NO, but I wish he was my boyfriend
Then she has to choose you or her boyfriend.
If he has any interest in dating you, he will not like your boyfriend. But maybe he already knows your boyfriend and they do not get along or else your boyfriend has a bad reputation that the guy knows about.
