7 months is not a long time to really get to know someone, I mean really get to know someone. I doubt either of you know everything about the other, just not possible, we are all too complex. You being nervous to bring this up to him also tells me that the communication between you two maybe isn't as good as it should be. Why did he all the sudden decide to tell you, any idea? He didn't know how to delete his dating account? Ok, let's assume thats true, he obviously was still going to the site 6 months into a relationship with you. A dating site. I hope this was just a simple mistake on his part. Working on your issues and putting your priorities in order first, then figuring out where he fits into your plan would be my input.
