Yes I am afraid history would repeat itself. Love is a risk though isn't it? I am trying so hard not to be paranoid... Maybe we should give people the benefit of the doubt. I guess I wouldn't be in a relationship with this guy if I didn't trust him at least a little bit. He doesn't really give me a reason not to anyway. I just hope he has Job's patience... it may take awhile and I don't want him to become exasperated...
Just be open with him, my ex used to always think i was cheating on her (ooo the irony), but i honestly did not mind putting her mind to rest, its when she would tried to catch me out when I was totally honest with her that irritated me, remembered once she went through my emails, she dug up stuff 3 years before i even met her...who is this, what did she mean to you, why did you say that, did you have sex with here, where is she now, are you cheating....lol, quite funny if i think about it now.
Just be honest with your guy and play open cards with him, if something is bothering you, raise it with him and talk like 2 adults.
