i just wanna give up at this point

im afraid my bf of a year is cheating... he has been texting 2 of his exes for a while now whixh i have openly expressed bothers me. he always gets mad when i say it bothers me. and now his phone went off and i checked it to see if it was important and his phone was in his recent calls and he has been facetiming one of this exes... then i checked the messages cause my mind never settles. so i looked at both exes texts... the other ex he asked to facetime and has been complaining to her about y she hasnt call him instead of him always calling her first. my heart is breaking. at this point im really starting to wonder if im even able to be loved...

ps. ivr been cheated on 5 times in the past
