Ok difficult problem guys please help?

so im shipping out to da marines very soon. im pretty stoked..but ive been in a relationship with my gf like for over a year now and just this summer she moved 2 hrs away to go to school and she wanted me to go visit her tommorow (of course i wanted to go to). Thing is on da last minute her just rite now her mom told her i couldnt...bummer right? and she begged so i guess her mom said he can come till thursday. i guess its cool but now i dont know wether i should go or not cus its gonna feel like her family doesnt really want me there which hurts me a lot. idk i also had a ride for tommorow and had to call it off blahblah so some advice from you yahooers would come in handy at this moment. HELP
