Should i be mad... or jus dnt care!

An old boyfriend of mine went jail to almost a year ago... i was in shock! so i went to see his mom jus to see what happened... but to make a very very long story short... him & I started dating again, i got 2 meet all of his friends and family while he was in jail. but now this past january when everyone thinks he's coming home, all of his ex girlfriend want to come out and say that they have been writting him and going to see him, but i didnt believe it at 1st because his mom and sister was telling me not to belive it. but then one day another ex of his said she's writting him 2. but what made me believe it was that his sister "my sister in law" was all of thier bestfriend.. i found out that she and his mother had been taking all of those girls to go see him:crying:... and playing me like a fool, so i told his sister to tell him that its over but then she gets upset and starts dogging me out to the other girls:shocked:. but i didnt say anything to her.."YET", but then out of no where he rights me a letter saying that he feels like i'm messing around on him!!!( i just dont understand why havent i cried about the situation yet and it hasnt even been a month ago:think: plus i have to get something to go over his name thats tattooed on my leg) but the next day after all that mess happened i found someone new... but i just cant seem to throw all of those love letters away...:smack:
