Can my boyfriend receive my text messages from another phone to spy on me?

If he knows your Apple ID and Password. Change the password here:

If he is the account holder of a cellular plan that includes your phone, he can receive call/text logs from the cellular provider.

Review any information that you may be sharing with your boyfriend by using Safety Check.

T mobile said he can request call log but he won’t get text messages because he’s not police or fbi …

Yep, that is correct. He can get both the numbers for calls and text messages that you sent and received. He won't be able to read the text, Tmobile just list the date, time, number, and for text messages it will say if it was just text or also a picture.
