Not real love then what is it?

I'm in the navy and my girlfriend is a civilian I met her in FL and it was love at first sight this p feb I got stationed in VA, she told me she wanted to come and start fresh with me. I'm suppose to live on the ship but I got and apt for her and her daughter trying to make them feel comfortable and at home as possible. So we all shared this 2br apt everything was so perfect I had everything in common with her we did everything together, I was so happy so then we start to fight then more n more each day. Watever she wanted me to do I did it to make her happy, it wasn't a lot but its the principle. I didn't talk to nobdy bc she was insecure I didn't go out. No now here comes april, she told me she is not ready for this anymore and that she rather be at home with her mom n dad. We had so much planned and had so much that we shared. Yes we struggled sometimes bc she didn't work I did everything by myself. N she wanted to go home bc the struggle was to much to handle. I'm so hurt and filled with pain I've done so much humanely possible to please and satisfy her every needs, she told me she was ready to settle down and start a life with me she told me I'm the best thing that ever happen to her I felt the same, no matter how hard it got I still tried my hardest. Now what I wanna know she it real love if somebody is willing to just walk out ur life bc they are homesick? I don't understand y it feels to hurt me way more I've been crying n crying she just acts as if it don't matter, she said she misses her mom n dad but she is 23 and I'm 21 n I don't even cry and whine bc my mom n dad isn't here and I'm I the military. Even wen we was around her family she didn't even wanna b there so I truly don't understand she has something good right in front of her and she's leaving me bc she wants her mommy n daddy, I hurts tremendously bad. ADVICE?
