Am i trying too hard? (relationship)?

[chasingrainb0ws]

I really like this guy, we have been on a group valentines date (double date with my best friend and his who go out) and we are going out again tomorrow night with them. Recently, i start a conversation and he replies once then ignores my next reply even if its a question?! Should i stop talking too him unless he starts the conversation? I know he reads and ignores because it tells you when they've read your message on kik and facebook. Its really annoying! Can it be he's less interested? He says he wants to go on another date but wont even talk to me
