My boyfriend is 916 miles away and we used to be so loving over text, used to even role play and sext (even pictures) now he texts me only once a day and he claims his working but he only works 6pm-2am but only texts me right before work and he's not sexually interested anymore nor does he plan to come see me or get me a plane ticket there even though he has the money, could he be cheating or does he not want to be in the relationship anymore?
