How Do I Tell If A Libra Man Is Really Interested?***?

I started seeing a Libra. First date went for drinks, and when the place closed he asked me to continue and go to a different bar. He has made me dinner and told me some intimate details of his life. Says he doest like to date alot, and what not. He has mentioned himself going out with his friends and talking about other girls. He has only done this once, but I am wondering if this a trait of a Libra to make a women jealous. He always makes eye contact, and I have not slept with him, just kissed, but we have spent the night together a couple of times and he is very sweet and is always cuddling and holds my hand at different parts of the night. I have never been with a sign that does this, or another man for that matter. But it seems like he has to be touching me or near me at all times. What traits should I look for to know if he is really interested or if he is just being a womanizer as some websites say about Libras.
