<human>: I have been going out with a girl for about five months. This is the first relationship for the both of us and things are going great. We love each other a lot and have a lot of fun together. Sometimes I just never want to stop spending time with her, until she shows her insecurities.

The problem is that sometimes she can be quite insecure. When she does it is very sudden. Sometimes she will start acting distant in the middle of a conversation. I usually have to push her to get the answer from her. Many times its some small comment I might have made or just that I didn't give her attention for something that sparks insecurities like what if I don't like her or that we do not share too many common interests or that we are so different so how are we together. I've noticed that this is usually sparked from her speaking to other people. I'm not normally the insecure type, but sometimes her being insecure gets me to think if she's into me. 

This sounds a bit worse than it really is. We do tell each other how much we mean to one another and how comfortable we are with each other a lot, but the insecurities is still an issue I need advice on. Especially because it can be so sudden. I usually speak to her after and then its fine. Its annoying while it happens though. Is this sort of thing normal? What can I do to make her feel more comfortable?
