Am i overreacting?

My husband went to the sex store by himself some time ago when i was out of town, and he was hanging with friends and strangers. Over where i live weed is legal, and he was doing weed with them also.

Anyways, he had ask me to drop him off at a "tobacco" store cause he said they sell the kind of pipe that he likes. And hes buying it for tobacco smoke.

As we got there, it was an adult sex store. I ask him why hes going to a sex store for a tobacco pipe? He told me they sell pipe cause he went in the store to kill time while i was out of town, and saw they sell the kind of pipe that he wants.

He told me he only got the pipe, not anything else. But i did not see we have any pipe in our home, nor see him use any, and ive only been gone a week and a half. And he doesnt want me to go in the store with him.

Idk i have a feeling he went there to buy things for some woman that he cheated on with while i was gone. Or am i overreacting?? Idk. What do you think?
