KGirl - new life, new stuff #2

Re: defining what this is, yes, we are exclusive (because that's important to me once sex is in the picture - once it got to that point I tried to keep it simple and said "I'm not OK with sleeping with someone who may be sleeping with other people" and he said "oh, no, of course I'm not, you thought that?"). He made a point to say he deleted his online dating apps. Then he started saying more things that I think have ramped up my expectations/etc. because they mean one thing to me, and maybe something else to him - like when we're out with friends or wherever he'll introduce me as "this is my girlfriend K", so using the word girlfriend, using the word "relationship" frequently, etc. In my mind I start to attach all this meaning to it, and maybe I should not.
