Personal insecurities must not be brought to the table of the relationship as it will most certainly cripple your relationship and anything you do along the way. If you have insecurities they can reveal themselves in many different ways, for example it can reveal itself in the form of jealousy, which in all essence is probably the most common way in which it reveals itself. Calling her every time she goes out with the girls, not letting her have any time to herself are two trademark signs of jealousy and insecurities in the relationship and will cause a lot of friction over a given amount of time. Some jealousy is good but too much is crippling. She needs to know you care about her but that she's not the only thing that you care about.
Other insecurities can be like calculating how much she's at work or how much time she spends with her friends versus the attention that you receive, which is a similar domain to the jealousy phase but it doesn't necessarily come across in the same way jealousy is. But an attention deficit in a relationship can be another crippling scenario. The fact is if she is with you then it is most probable that you don't need to have any insecurity issues whatsoever and that your relationship will flow smoothly and without too many hiccups.
Try to be secure within a relationship as much as you possibly can and ensure that you also don't prey on any of her insecurities. This to can be fatal for a relationship and can cause angst and anxiety on her part if you all of a sudden begin to stay out late, spend more time with a friend who happens to be female. When you start talking about other women around the house is just another stupid idea if you value your relationship with her. It's a good thing sometimes to test that she cares but too much of it is not advisable. This is good in making yourself secure and you'll find yourself having no jealousy issues because you will have nothing to be jealous of. What you shouldn't do is to play too heavily on any of your or her issues to ensure that your relationship go along well. Talking to her about your problems in a good manner is more advisable. You should be able to go through your relationship in a relaxed manner that ensures you both have a seamless relationship with no bumps or hiccups and you will both be very happy. You can remain relaxed and laid back about your relationship.
