Did I Just Ruin Things With Him? I’m So Dumb I Was Confused?

We have been dating four months. But, since summer started we have barely talked or seen each other the reason is because he is away sooooo much. Well I guess I was annoyed with the fact that we barely ever talked and when we did things didn’t seem right. The last time I saw him was July 14th. I don’t even know where he is right now.
Well a few days ago I got up and I just didn’t like him all that much anymore. And while I was up at my cabin ( i just got back yesterday) I was flirting with tons of guys and I almost hooked up with one of them. Anyway, so tonight on facebook we talked which was the first time in like 9 days. Here is our conversation
Me: Hey
Him: Hey
Me: so how are you
Him: I’m good, u
Me: im okay
Him: why only okay?
Me: i’ve been thinking maybe we should break up idk
Him: idk
Me: ?
Him: it’s up to u
Me: do you wanna break up?
Him: no
Then he logged off
Then 10 minutes later I called his cell and he didn’t answer. Then he texted me here is our other conversation
Him: i’m sorry
Me: Can I call u i need to talk to u
Him: no not really it’s long distance
Him: ive been away alot and i haven’t had cell service
Me: i don’t know what to do
Him: same
Me: do you think we should break up?
him: no
Him: i love u
Me: i still wanna be with u. now I feel like a b*tch for mentioning we should break up, i love u
Him: i wish i could stay in contact but i cant
Him: i can’t just ignore the fact that u wanted to break up
Me: I know i had just been thinking that breaking up was the right thing to do idk why but i did. I guess i was confused idk im sorry
Me: im sorry
Me: i know your probably mad at me and i understand why u would be, I’m sorry i’m a bad girlfriend
Him: no ur not
Me: yeah i am i shouldn’t have thought about breaking up with you
I don’t know why I changed my mind so suddenly I still do like him. i hope I didn’t ruin our relationship. I’m soo stupid.
We haven’t talked since. I don’t know what’s going on?
