OK.
You can be both lonely generally and in a mood to be alone at a specific time, so I would not be surprised if sometimes the body language would be the same. If initiating a conversation is the only way you can know, I hope you also accept responsibility for any possible disturbance this causes to the other person.
I don't think you have to be a father figure to treat women with respect. I find it interesting that you conflate the two. Why do yo think that is?
You seem like a relatively intelligent person. In fact, you seem intelligent enough that, when I make a reference to something I had said a mere two paragraphs earlier in the same post, you are more than capable of making the connection between the two. Nor do I believe that you were unable to understand the earlier paragraph, in part because you would have asked. Therefore, I can't see any honest way to interpret your last two questions. You know the answer, but rather than be honest about that, you wanted to score some rhetorical points. How well does that speak for your politeness and respect?
