Depressed

I dont know what happed but my ex bf broke up with me about a month ago .He told me he really depressed and stressed .I understand why and know its the deployment .Since I got in this reationship I deal with his mood going back in forth .One min he tell me he hope this work the next tell me something like I dont think your the one .He called me 2 since the break up the first time he told me he felt like **** and got my package .He just called me last weekend and he talk about how wanted to see picture of my new hair cut and my mom put it on fb and he put I LOVEEEEE .He told me how he wishes he was there to hang out and stuff and told me he loves me when haging up the phone .When he broke up with me the agreement was to get back togeather after the deployment and he be home for a month .Its been a week since I hear from him but we sound like we where ok but took him a month to take down the in a reationship .I dont understand why it took him that long and why now ?His mom lives in another state and his anut lives home with his father his aut and mother fight all the time .But his mom told me he be done deployment early and sending him back to his base for 6 months .I dont know if I will see him or not .Thats when the next day he changed his facebook status and how his aut put well maybe your next girlfriend can spell..there plenty more fishes out in the sea .I dont know what going on .His mom always say there someone in his facebook .Sometimes I wounder if someone did it or him or even what happing with him .
