Should I tell my ex that I still have feelings for him?

Me and my ex boyfriend broke up about a month ago. I really really didn’t want to break up with him but toward the last month of our relationship he was acting suspicious. Since we lived about a hour away from eachother we talked on the phone every night. But at that time he just seemed like he didnt want to talk to me anymore. i dont know what i did. so i asked him is everything ok between us? and he said that it was just hard for him to have a long distance relationship and he hated not being with me all the time and that when we werent together he was feeling depressed. well that kinda gave me a clue about his real commitment to our relationship. But what i dont understand is that when i would ask him if i could come over and see him he would seem to make up an excuse. I mean if he was feeling depressed about not being with me all the time why would he make up excused not to see me??? so i no this is a bad bad thing but he gave me his password to his myspace earlier in our relationship. And at that time i felt like that was the only thing i had to really figure out what was happening. So i checked his inbox and i found stuff in there about him with some other girl and how they wanted to hang out and they had fun the last time they hung out. thats when i called him up and told him i no about this other girl and i think its best that we dont see each other anymore because u obviously dont love me anymore.
Now that were broken up he still says hi to me on msn.. and he asked so how has life been treatin ya??…….i dont know i’m confused when he talks to me on msn. it seems like he want to still be a part of my life and know whats going on in my life. but its hard to be friends with him when i want him back sooooooo bad and still have feelings for him. but if he really wanted me back you’d think he would have said something to me by now or something…i just dont want to get hurt if i tell him that i have feelings for him still and he say that he doesnt have feelings for me…please someone help me do i tell him???
