Broke up with girlfriend but I miss her?

I m 21 and my ex is 18 and dated over a year, we are both still in love but why did we break up? see it all started when I got a job on boarder Patrol so Im not home as often anymore.

She hates this job because I see her a week for every 2 months and a month off at Christmas, I tell her that this is totally necessary because it sets up our future, an apartment and a life I want for us.

She just wants me home, now I m home, she s acting strange, not wanting to kiss, hold hands, anything. A week of that she refused to tell me what s wrong so I pulled the plug, I know she loves me, that s how confident I am. I m she sent me text messages saying that she is the one at fault and she wants to still hang out.

I ve played it pretty classy, I m pissed off but she doesn t know that, I just want her to understand what I m doing for us, but now I m home and finally here, she doesn t want to know me? What should I do?
