TITLE: [18M] Really struggling to start basic conversation with girlfriend [17F]
POST: Hoping the makes sense. So I've been dating a girl who I really like for the past month or two. We have known each other for about 6 months now and initially got along really well! However I feel as though our relationship is a bit...dull at the moment. We haven't had any proper, long conversations about anything. For example today we couldn't sit in the same room for 5 minutes before we run out of things to talk about. To resolve the problem I will usually just start making out with her, which is great!! But I don't want this turning into a purely sexual relationship.

When I see her in her normal social group (other boys as well) I wish I could be as "fun" or "close" to her as they are (if that makes any sense). 

We can't even have a decent flowing conversation on Facebook... Depressing stuff for me, I'm not sure what's up. Sexually we are awesome and love each others company. But other than that it just feels... Meh.

Is it possible we just aren't made for each other?
TL;DR: 
Struggling having fun, decent conversations with current gf. Not sure what's up, generally confused and depressed.
