Think he's gonna dump me...help!

Think the guy im seeing is gonna break it off with me!
Last night we were kinda talking on the phone but the conversation wasnt really going anywhere so I told him "im gonna go this conversation isn't going anywhere" then phone cut out so we never said proper goodbyes.
I said him a text saying "goodnight then" and he sent one back saying "it cut out. night".
I saw he was on fb but he didn't start any chats with me

I haven't heard from him since the "it cut out. night" text im worried he's gonna dump me.

Should i text him something? What should i say?

I think he's out with a mate atm should I text him and tell him I wanna come and see him later..rock up unexpectedly?

Im going outta my mind atm.

don't talk to him right now. hahaha. talk to him like normal after a few days
