is this normal?

Karina
I've been dating for 2 months and it's been a long distance relationship the whole time. I last saw him in person on August 7th. We talk, Skype video, text, etc a lot, almost every day but here lately there's just been a lull in conversation-basically it's just good morning/goodnight and "how was your day?"... is this normal? It's hard because that communication is really all we've got at this point. Sometimes I get super worried that I'm not interesting enough or something...
Any advice?
