Ask AI: I am a straight guy and last night I visited my male friend , he was alone in home , he watched my lips while talking

What I can understand from your statement is that your friend might have been showing subtle signs of attraction towards you. It's important to understand that it doesn't inherently mean anything bad or good, it's just how he might feel. I would recommend discussing it openly but tactfully with him if it's something that's making you feel uncomfortable. Honesty and communication form the basis of every important relationship. However, if you feel this could ruin your friendship or cause conflict, it may be better to let it rest unless he communicates his feelings towards you. Also, it's possible that you may have just misread the situation. For now, you can continue with the friendship as usual until there are clearer signs.
