So this girl is in my school and we hang out sometimes with many people. My question is should i become friend with her if she has a boyfriend and i like her?
If you like her romantically and she has a boyfriend, it may be best not to be friends with her at this time.
If you were to become friends with her, you may find yourself becoming more and more emotionally attached to her.
This could lead to a lot of heartache for you.
You will keep looking at just about any kind of attention that she gives to you as a sign of her being interested in you when all she is doing is being friendly.
