relationship issues

Skylar
So for the past year  my boyfriend and me have been so busy with school jobs etc life. That we really forget to have time for eachother  since we don't live together it's very hard to see eachother we have opposite schedules sometimes time and I understand work fully but I make the effort to be with him when I possibly can but when it's time for him to make effort he dosnt . And for the passed year everytime we have sex he gets on a rant about having a 3 sum  and about 2 diffent girls one in particular cause she's a virgin . I don't know what this means ? Am I not good enough anymore . He dosnt  seem to be all the way there or in to our relationship sometimes and it kills me to the point were I think he's talking to someone else . Cause I never get to see his phone or anything idk what to do here my life is like in a carousel it never stops spinning. Help advice
