It's super annoying to me. Because you feel like first they don't care and second you are annoying/bothering them. I had a ex like your bf. I always had to text first and had to keep the convo going which I hated.
If you feel this way, Talk to him about it. Don't just assume because something might be going on. I mean sometimes I have to much on my mind to talk to anyone or even text.
I'm guessing he is around his 30's like you so really it could be work or anything. Also I know it's hard but don't text him inless he texts you. No matter how long it has been since he has spoken to you. I mean it. He will amke time for you if he cares enough and you are worth it to him. Trust me! :)
