Is it okay to be slightly clingy in a long distance relationship?

[Sarah]

I've been with my boyfriend for a year now and for the last 6 months our relationship has been a long distance one. We skype with each other every night- except during exam times when we mostly message each other. By the way, I'm 22 and he's 24 and we're both university students.

Recently, I've been quite annoyed on a number of times with him and the reason is always the same. When we're skyping, he's usually doing something else at the same time (sometimes just scrolling down his Facebook page or just reading up on some random fact). He replies to whatever I'm saying but doesn't give me his full attention like I do. The reason is: I kind of miss him during the day and look forward to the time we spend together over skype at night.

Is it being clingy to get annoyed over that?

Thanks
