confused

UGH! it just gets harder and harder for me to let my ex christian go. i love and miss him so much.. and i feel like an asshole. He called me last night when i was out with my new guy Chad. I didn't talk to him very long and he seemed annoyed that I wasn't focusing on him (I would of been too). He is still madly in love with me but he's moving to hawaii to be in the marines. and i havent been on myspace in 4 days so its a lot easier for me to be less tempted to talk to him since he doesnt have a cell phone right now thats are only way of communication except when someone else lets him use their phone.
so im really depressed about it because i know he will shun me if he finds out.. i haven't told him yet.. i dont know if i want to. I hate when i fall in love with someone and then I don't know if thats what i wanted and i cant really get out of it because he wont wait for me and he'll hate for me to date someone else (as i would feel the same for him). this suuucks!!
just straight up fucking sucks. im so upset i dont know what to do. i hope im making the right choice....
