Please help... I desperatly need edvice before I loose a great guy..?

Mi Nd my bf have Been going out for bout 9 month..at da beginning our relationship was perfect..I checked his phone one day Nd found his exs number.. He had been talking to her.. I confronted him Nd he said she was calling him so he called her back Nd told her to stop..second time around I found naked pictures of his ex gf.. She had a bra Nd underwear but it's still naked pics to mi.. Once again he said Dey were all her..nd ge wasn't talking to her..After dat day his jealousy got even worse.. I stoped going out so he wouldn't get mad but everything did.. I deleted everything dat had to do with the Internet so he wouldnt get mad.. But from der on it was a different fight everyday..I got my facebook back Nd added a couple of friend.. One day while mad at my bf I wrote to one of my childhood friends Nd said dat Been with my bf was like been alone.. Pointless.. Nd my bf read it.. We broke up Nd got back.. I didn't start da fights but I know I didn't help resolve dem either.. This was all 6 month into da relationship..one day I got so fed up with all his jealousy Nd decided to go out with friends from work.. Long story short.I met this guy..i was so angry at my bf for accusing mi all da time..dat all I wanned to do was cheat.. But I couldn't bring my self to doing it.. All I did was take pictures with Dat guy.. Stupidly I kept those pictures..we broke up for a week but ended up getting back together.. We both apologized Nd talked alot...it started good but...little by little he started going back to his old way..questioning mi about every single little thing..not dat I had Nething to hide.. But I was trying to stop da fights..was da old things coming back nothing had changed.. I went crying to work one day Nd a good friend of mine which had always gave mi edvice was der.. He was having similar problems to mines..long story short.. We started talking.. But it was strictly talking.. My bf found out bd we broke up.. I do love him Nd want him back..
