What should i do to entertain myself but still being faithful?

Get a hobby - photography, scrapbooking, anything. Just please don't cheat on your poor boyfriend! (I know you said you wouldn't, but lots of people do, unfortunately). Maybe you can go shopping with friends, do volunteer work, or something like that.

Go to the gym with friends or take up a sport

Hobbies are a good thing. When you miss him in the bedroom.........get something with batteries. ;D

My sister is going through the same thing. She works double shifts when shes needed. She also hangs out at his moms house quite often. She tries to not go out to often though that way she isn't even tempted. Take this time alone to watch movies that he normally wouldn't watch. Go get manicures and pedicures. Girly stuff, stuff to make you feel better and pass the time. You'll be suprised how fast the time flies when you're having fun doing stuff for yourself, and he'll be home i n no time. Enjoy yourself and good luck!!! Semper Fi!!
