So we dont have sex nearly as much as we used to and weve only been in an LTR for three months.

I know this is definitely my fault, stepped too much into her frame among other beta slip-ups, just part of the learning process.

My question is how to break up with her without nuking our big extended friend group/ community... or if there are any suggestions as to whether the relationship can be salvaged.

Also, I genuinely dont think shes cheated on me or been unfaithful at all (though she easily could, AWALT).
