Should I be flirty or casual?

I like this guy. We started talking a little over a month ago. He used to show a lot of interest and it really seemed like he liked me. He's always been a pretty boring texter 90% of the time. But a lot of times we'd talk to eachother all night and then when I said I was going to bed he'd say "no. ". He used to call me beautiful all the time and call me things like baby and babygirl. But he's been weird lately. We haven't really been talking like we used to. I texted him a few nights ago after not talking for 4 days and we talked for a little. But he was being boring so I eventually stopped replying. I have a huge feeling he's talking to other girls. But I guess I can't assume. His birthday's today and I'm not sure what I should do. Should I just say "happy birthday. " or put a kissy face (the emoji on iphones)? He used to put them all the time but since he's been weird I'm not sure.

Casual. Probably has a girlfriend or something.
