I met this friend six months a go and we being very close,the thing is am just confused because, I don't know if she is a lesbian or not because she keeps on hugging me very time we meet sometimes she kisses me on lips, touches me on my back, recently she has stop hugging me, or kisses on the lip, instead she huggs my friends and pretend like she doesn't sees me, but we talk normal like nothing is wrong, am just don't understand why she is behaving this way is she breaking up with me or no help me understand!

Just ask her. Talk to her about it. Tell her how you feel.
