Does he like me, im meeting his mom??

short as possible, me and this guy began dating a couple mos, we didn't expect things to happen at the beginning, he got out of a relationship a couple mos before that broke his heart. we started being friends and talking about his heartbreak, things just happened and we are now "open" dating p/the best for us both. he's not ready to commit, im not ready to commit w/him being i know he's not over the ex completely. we have great fun together, are really good friends and stay in contact daily. tomorrow he is taking me on an all day road trip and on the way back down, he suggested we go meet his mom for dinner, bcs we will p it on the way down. i know guys don't just take any girl to meet mom, but at the same time, im thinking, well it's convient bcs we will already be in the area.... what do you think???
