What’s the deal?!

So my boyfriend out of nowhere just stop answering my text and calls.....like it hurts and it’s just weird. Usually if he’s mad he tells me and just gives me an attitude and we fix everything. This time I’ve been calling him for a whole day now and the phone doesn’t even go to voicemail. It just rings and the messages say delivered..... 😩😩😩💜 idk why this happened. Idk if he’s ignoring or if somethings up but I’m hurt and scared. What do y’all think? Let’s hear it.
