We used to work together, and he initiated at first and gave me his number to text him. We texted a lot for a few days, and now I'm always the one who has to text him first. I let it go for 4 days once and still heard nothing. Most of the time he responds and seems happy to hear from me. I'm starting to feel like I'm bothering him. I like him and he seems like he's interested too, so why am I the one having to initiate? We do live a few hours away from each other, do you think maybe that's the reason why he is backing off?
