Boyfriend Trouble!!

So my boyfriend of 2 years always leaves me hanging when we're texting, like I get it, I work and he doesn't but 10 hours? You'd think he would bc he doesn't do anything but come on!! Yet when he's sexting me, his messages are faster than the speed of light? Like? And his excuses are, I forgot my phone, oh it died, blah blah blah. Okay but when your with me you're texting like 5 girls and your phones fully charged? Is he bored with me? I can't lose him
