Does this girl like me?

She might like you. LOL and HAHA is not flirting, it is just web and text lingo, so don’t read too much into that. Generally, a girl will not initiate conversation with a guy unless she is interested. So if you are interested get to know her and see if your attention is reciprocated. If it is, then ask her out. Be careful to wait to long to ask her out if you think she is interested, because she will feel rejected and start to think you are not interested.
