Short replies


So a guy I’m kinda interested in only reply’s back with short one word texts. Super annoying. I’ll ask what he is doing, nothing. I’ll ask what’s up or make a couple sentences so he can reply and it’s all ya or why. Why is it hard for him to keep a conversation going? Like I just don’t understand how someone who says they like you and wants a relationship can only have one word responses to everything. Help ladies idk what to do about it.
