Women are more complicated than men, which is why it could be hard sometimes to tell if she really likes a man.
On the other hand, men love to keep things simple, which is why if he really likes you, he would want to see you again but if he isn't, trust me, you are getting no call back from him.
So what are the reasons why a man won't call a woman back? Carly Spindel of All Women Stalk lists 7 of them.

1. No chemistry: Chemistry isn’t something that can be explained. A man can think a woman is beautiful, well-dressed, and very sweet, but for some reason he just doesn’t feel a connection with her. Chemistry is one of the main reasons why men don’t call women back.

2. Rudeness: Sometimes women forget to be polite and ladylike. Perhaps the guy wasn’t what you expected. He might have been shorter than you thought he was, a bit heavier, or, he looked nothing like his pictures. Regardless of the reason, being rude to someone isn’t cool.

3. Lateness isn't tolerated: Men can’t stand when women are late. It rubs them the wrong way. Being late shows a lack of respect for the person you’re meeting. It’s also really, really inconsiderate. I always feel like an idiot when I’m kept waiting. Don’t you? If you’re late to a first date with a guy, it can easily put things in a sour mood from the get-go and ruin your chances of getting asked out again.

4. He's not just that into you: Your date could have found you attractive and really fun, but he just didn’t have the sparks. He wanted fireworks, and sadly, there were none. It happens all the time. Sometimes men think women are fabulous, but the necessary attraction needed to foster a relationship is missing. You could have had a great time, but your date just wasn’t feeling it. Don’t take it personally; there are plenty of other fish in the sea.

5. Choose your words wisely: Men generally aren’t as sensitive as #women, but believe it or not, it’s possible for them to get offended. Kindness is contagious. It’s important to always be nice on all dates. Everyone, and yes, I mean everyone, deserves to be treated with respect. I certainly wouldn’t want to go out with someone again who hurt my feelings.

6. She was a hot mess: Baggage isn’t sexy. There’s such a thing as having too much baggage. The important question is do you have a carry on or a streamliner? If you have a little bit of baggage, that’s okay. But if you have a full-fledged steamliner, your date isn’t going to be eager to see you again.

7. He isn't commitment minded: Often, men don’t call women back because they’re not emotionally available. Sure, they might have thought you were great. And, they can even see themselves dating you. But right now, well, they aren’t ready for something serious. They want a fling and they know that you don’t.http://pulse.ng/relationships/single-ladies-7-reasons-that-guy-didnt-call-you-back-after-that-date-id3660636.html
