Please help...boyfriend buying condoms...not for me...?!?!

Ive been dating this guy for about a month or so...so far it has been really good, our friends introduced us...we spend almost everyday together...he called me a lot over Christmas when he went home to Mexico...it came an ice storm and he stayed over this weekend...we went to the store and I was helping him find some things...he looked at the condoms and said, I need some condoms too I said Try the NaturalLamb ones, theyre the best...he stuck him in the cart...we dont use condoms bc I take birthcontrol and we are both std free...he then said when we were in line...you know...i need all the stuff that is in my cart...all of it...the razor, the bread, all of it...is he just trying to get a rise out of me? Ive not been emotional with him and Ive never asked the status of our relationship. Last night we went out and i didnt pay a lot of attention to him...he made fun of my outfit and then called some girl and asked her to come hang out with us...whats up with him?
