It's it normal to feel a little insecure?

I have been with my boyfriend for almost 2 years now and I am the most insecure person ever. I don't like when he adds/talks to girls. I've come to realize just because he adds them doesn't mean he's talking to them in a relationship way. We have had problems with that issue but I'm getting over it. YES it is cmpletely normal to get insecure and jealous over that!
