I have a question that doesn't have to do with bowling directly, but involves my teammate.  

Scenerio, teammate texts me if I wanna join him for bowling Sunday morning, my gf is sitting next to me and I ask her if she would want to join, (she doesn't bowl and has a physical limitation/disability), she asked me if she could try as well.  I text back asking if he would mind if she came.  His response

"I don't care.. Bring a shovel to clean her off the approach when her leg gives out..."  

She and him have maybe said 5 words to eachother ever, but know of eachother.  I took personal offense to this and declined going bowling the next morning.  We bowl together tomorrow night and I definitely feel animosity towards him.   He and I are 2 of the top 3 bowlers in the house.  I will also see him this Friday and was thinking of pulling him aside and just talk to him then and explain how he disrespected me by making such a "wreckless joke."  In general he doesn't have tact and tries to make poor jokes, but I feel this crossed a line.

any advice on how to handle the situation.  Thanks in advance.
