I met this girl who I've started to have a great connection with. We have been seeing each other for a month. I really liked her and told her I wanted to be in a LTR relationship but needed time to end relationships with other girls. After I realized she would be gone for 3 months due to an internship and we would only be together for another month, I pulled back and told her we'll date exclusively when she comes back. She does a bunch of shit tests but I've passed them all to the point where I have a obedient girl who will do whatever I ask her. I tell her when to pay, when we are hanging out, when we are having sex. She knows I'm seeing other girls and she knows she can see other guys.

I feel like her dating other guys is limited but it's there. Girls and computers always have backups. She would prefer dating me, since I have gotten further than other guys with meeting her friends. I'm ready to be in a LTR but not for 3 months long distance at the beginning. I could always say yes to the LTR and then do whatever I want. However am I approaching this correctly in telling her to wait?
