How can you know that your boyfriend loves you after you visit him at his place and there is a girl there and he did not introduce you as his girlfriend?

Answer First of all I don't believe for one moment that he loves you or he wouldn't have other girls in his place, and he would have introduced you as his girlfriend, which you say he didn't. Sometimes we have to use our brains and ask ourselves why he wouldn't introduce us as a girlfriend or boyfriend and come to the conclusion that either he's not proud of you or he wants the other girl to think you are only a friend, maybe he's sleeping with the two of you. I'd move on if I were you.
