Should I be worried?

Molly

Ok so last night my boyfriend said he had to keep his daughter another night while his ex gets stuff done in the morning. That’s fine! When he has her however I usually get lots of pictures and we still continue talking through the night. And last night, I got nothing. He left my messages unread for 13 hours until this morning and said his Snapchat was having glitches or whatever.

I have a history of being cheated on, and I’m not going to lie this worries me a little bit. Should I be? And how do I ask him about it.
