Thank you for writing your concern to YourDOST. You didn't mention, How long have you been with her Clintrod? Also, how do you feel when you are with her? Has there been some instances which give you a doubt that, she can cheat on you?
I can see that, you know about all her past relationships, so, I am assuming, she must have shared about them with you, and, still you chose to stay in this relationship with her, Did I get that right? If yes, what made you to stick to this Clintrod?
I do understand that it is very human to get different thoughts, at times you question your decisions too.. and that is really natural Clintrod. You did wrote that now she is completely faithful to you, but at the same time you do face some trust issues,yes?
