Most Helpful Guy
Trust is earned, not just given.
You don't have to trust her, until you actually trust her.
Don't feel bad, you can still love her.
You're just being smart in my opinion.
Take it from me, I've trusted women completely and blindly and been totally fucked over before.
Just enjoy her while it lasts because there's no guarantees.
If she does turn out to be loyal long-term, that's just a bonus.
