Boyfriend problems

Me and my boyfriend have been going out for about seven months now. I love him to death. I will try to do any thing for him. I don't know what to do though because I've been wanting to breakup with him a couple of times before. Then again I still want to be with him. I have been in a bad relationship before him and I was in that relationship for about two years. I was so hurt from my last relationship that I did not want to have a boyfriend and I was going to be all about my self ,but I didn't want to be selfish and let one guy mess it up for all the other guies that were trying to be in my life. I didn't want to keep shuting peoople out. So I gave the guy I go out with a try.I wasn't sure if I should though because I am afraid of being hurt again. My boyfriend means the world to me and I care about him and love him with all of my heart. Its just I don't like females calling his phone and talking to him and telling him its like that now I heard you were all hugged up with a girl thats your gir! you didn't tell me you had a girl,ok thats how it is you all with me then now you all hugged up with your girl. then some girls call like late at night at like 3 or 4 o'clock in the morrning. I think that is so disrespectfull exspecally because I am around and hear it and see it. I mean don't get me wrong I don't mind females calling his phone if there friends thats calling in all but I think that they should respect me when talking to him and he should respect me when talking to them as well. The thing is that later on I would question my boyfriend about the females that calls him and the one the called him boo and he would tell me their people from his job (friends). I believe him then I leave it alone then something I would be chilling at his house Like the next day and a female would call him and I would be like answer your phone he doesn't answer so I answer it and put the phone up to his ear and the girl would ask him if he was bussy or something he would be like yea so the girl on the phone would sound all made and sad and be like ok I will just call you later or call me later or something and he would act like he doesn't want to talk and be like all right. I mean this are the little things that bother me because I was hurt once before and I do not know what to do I mean I believe him to a sertain extent. I mean I trying to at least and I really want to be with him. It's just that I don't know he gives other females reasons to like him because he talks to them in a way that they think that he likes them then he says he don't like them and he didn't know he was giving the females reason to like him. I think he likes his ex-girlfriend still. He talks to her every once in a while but when we get into it he will call her. If I go throuh his phone and see that he called her and be like so why did you call so-and-so he would be like just to see how she was doing, but doesn't try to call her any other time. He will call her after she calls him to see how he is doing. I already told my boyfriend that I have been hurt before and he knows what I went through. I've also told him that I am not into games. Therefore I'm not trying to be with him if he is going to cheat. If he wants to cheat he can be with someone else. I've told my boyfriend that I am trying to get myserlf right. I'm going to college this fall I am getting older and maturing and that I wanted better for myself. So I don't have time for the games cheating and just wanting to see how many girls or guys you can get was for when I was younger and I have done all that and I am 18 years old now I getting older and being more serious trying to get to know what I want for my future because I want a husband not a boyfriend or a babies daddy when I am 25. So I am really confussed and don't know what to do. I just need so advice. thanks!

sounds like that prick is cheating ! if you want to get eventake his cell phone when your over his house ! be like be right back I have to wash my hands thare sticky .. when you have his phone put it on silence then turn the water on and wash it out ! then if your really bad break it in half and whip it out the window or just flush it ( may get clogged ) or throw it away in the trash.. then ull never have to worry abt girls calling him =]
