stop sharing texts between phones on same account

It appears that both of you are sharing the same Apple ID. This is the underlying reason why you are getting his texts. Both of you should be using separate Apple IDs so that the data, such as texts, calendar events, notes etc, do not overlap.

If you must share the same Apple ID, then there is a workaround which is not clean but will somewhat do the job.

For the Messages isolation - Perform the following on both iPhones:

Open Settings ➔ Messages ➔ Send & Receive: Ensure that ONLY ONE Phone number is checked and that is the phone number of that particular iPhone. No email accounts should be checked. On the same screen, select start new messages from and choose the number of that iPhone. On the same screen, select Text Message Forwarding and set the switch to the OTHER iPhone to OFF.
