Josh (May I call you that instead of SP?),
My first inclination is to tell you that the bells and whistles are going off for you. Trust your instincts. This doesn't mean something concious or intentional is going on but it is causing you some ditress. As such you need to let him know as your 'partner' (key word here), that sometimes this feels uncomfortable for the reasons that you mention You say it doesn't but re-examine the quote
it just seems sort of... wrong.
This does not mean you don't love him, that something weird is going on, you don't or shouldn't trust him or he should fear causing triggers. Just that it is causing you some distress. Let him know that sometimes this feels appropriate and makes you feel very warm and loved and that other times not.
For some people I suspect that this might be a healthy fantasy to some extent (Help me guys on this one?). For others, it becomes co-dependency.
There is a time and place for everything. You are young but you are an adult now Josh. You have the ability to bend and shape things to a degree as you like/want WITH your guy. Be an active participant in the decision making. And trust your intuition a little more. I am learning this as I go on in life. The bond that links your true family is not one of blood, but of respect and joy in each other's life. Rarely do members of one family grow up under the same roof.
