The real man, the man who loves you, will respect you and appreciate you for your strong opinions. But, on the other hand, there are men who will tell you that you are wrong or agree to let you think what you want, but without believing that your opinion is important as theirs.
A man who loves a woman will encourage her to follow new opportunities and experiences. The real man may introduce her to a lot of new things, but the most important is that he will never force her into something she is not comfortable with.
Men who love women will tell them what they need to hear. For example, if you ask him how you look in a pair of jeans and he tells you that you should change, that does not mean he is evil. He is just honest. But, if a man who tells you to lose weight, he insults the things you like, or your style. You should know that he does it because he does not respect you and knows that if he is talking to you like that, he can get away.
Do you want a man who will text, call and want to be with you 24/7? Some women think that this sounds great, but they should think better of this, because constantly checking up on you and needing the reassurance of their place in your life, indicates that he is in this more for himself than for you. A man who loves you will certainly let it show both emotionally and physically. A clingy man has emotional problems and wants to talk to you so he feels validated, not so you feel good.
It is natural to protect something you care about. In a case he keeps you in close sight and his arm around your shoulders while you two are out at the club, that is great. But, if he does not let you go anywhere alone or starts fights with men who try to talk to you, then he is possessive.
A man who is interested in you will talk to you when the times are convenient for him. This should be expected, if the relationship is new. But, if you two have been official for a while and he still only seems to talk when it is good for him, then it is obvious that he is not in love. You will know that he is the right man, when you take a step back and analyze your relationship, your interactions and your overall level of happiness.
