No, if you’re seeing each other In Person* on a semi frequent basis (once a week), it’s not e-tethering.
E-tethering is when a man texts you back and fourth but actually doesn’t make any effort to see you. He might make plans but they’re never concrete (vague dates) or they always fall through.
If he makes concrete plans to see you and follows through with those plans, I wouldn’t worry too much.
