Baby Come Back

Ash • Boy oh boy am I a train wreck.
He never texts me first anymore and I feel like I'm the one doing all the work to try to see him and talk to him. I asked him what was wrong because he'd been really quiet towards me lately, but he just said he's been really tired (which I mean is valid for him but not really helpful). But whenever we do talk it goes pretty well, I just feel like I talk too much and scare him away. I think I'm bothering him but I so badly don't want to lose him. 
What did I do and what can I do now?
