[b]if I got u clearly u said he normally threatens to cheat on you whenever you guys have a quarrel or jokinly,but u didn't tell us if his attitude towards you have changed,if he no longer show you love as he used to,it may be a joke,it may be just a threat,it may be happening already,but honestly there is no evidence to nail him to his threat or his joke,I' would advice you to watch him closely and find out if he really cheats on you,other than mere speculations,because if you are wrong you may force him to really cheat on you.[/b]
