His ex girlfriend problems. Was I right to be upset or am I just freaking out?

We can all get that twang of jealousy of past girlfriends and girls that are his friends but i think you were totally reasonable to get upset over it but i wouldnt cause a fight with your guy, that would give her satisfaction and him a needed shoulder to lean on which could be hers and you dont want that i would explain to him that it sort of hurt you because you treasure the privacy of your relationship and you would hope he does too tell him how you feel because communication is truly key to have a trusting healthy relationship i say this from experiance and today i have been my boyfriends longest relationship and be confident in who you are not for him but for you !!!!!
