indecisive on what to do

I really like this guy I’ve been knowing for years (since middle school) and we reconnect and decided to start talking and everything was going good but then after a while things started to change he is in the military so I understand we can’t talk much because he is busy and stuff, he told me he was coming home for a week for Christmas and he was supposed to come home tomorrow (12/21) but he came in today (12/20) and didn’t tell me anything about it not even a text the way I found out was through his Snapchat I was really upset and now I don’t think he is taking this serious, I’m really upset because I feel that he is just wasting my time, I’m starting to feel like he just wanted someone to talk to when he was away, I want something real, I want a serious long term relationship, I’m tired of these little boys breaking my heart, I want a man that knows what he wants in life, I want to get married have kids and grow old with a man that I truly love

What should I do?

Should I tell him how I feel?

Should I just end it?
