understand why men do what men do

I don’t understand it… We were in the car, his phone rang, I could hear some woman on the other end. I ask who it was, and he said it was his friend justin. I told him I could hear a woman & I asked again who it was. He told me his friend was using his womanly voice. I looked at him, opened the door and asked again who it was. He finally told me it was his friend Wendy. He said he didn’t want to tell me because I would be upset!!!
I wouldn’t be upset if friends who are woman call, I’m upset he lied and that and that he tried to hide it from me! It makes me wonder if he was cheating on me?

Why is it that your guy friends still hit on you, even when you’re single, and they know you’re not interested! I went to the movies with one of my guy friends. He’s know’s that I’m in a relationship that I’m about to end, he also knows that I want to be single for a whie. So can someone explain to me, where he would get the idea that he should try and feel me up? Really, what was he thinking? Of course, I said something immediately, but still!
Can someone shed some light on this matter for me, thanks.

Why do men say they want things when they really don’t want them?
I doesn’t make sense to me why men say the want something, only to find out later that they didn’t really want it. I could understand if they were saying these things to keep me quiet, but they’re the ones who bring it up! Are they saying these things, hoping that it will make me happy? It actually only annoys & frustrates me. It makes it hard for me to belive things when they randomly lie to me. I just don’t understand it.

Why is it that some men will do anything to be apart of your life, regardless of how rediculious is?
Why is it hard for some men to understand that a relationship is over?
Why is it that men say that they don’t want marriage to & kids at the begining of the relationship, then 4 months later they can’t stop being married & having children? This will scare any woman away!

Why do men, say they’re going to do things, when they never wanted to do them to began with?
Why do men pretend to be someone they’re not just to get a date?
Why is it that I feel like I could explain something a million times, and yet his response to what I am saying will have nothing to do with the topic of the conversation?
Why do I always seem to find the jealious type?
Why do men get so jealious?.... they have no reason to.
