what does this mean????

so i have been seeing this guy for about a month now...we met at a club and hit it off and have this AMAZING connection..even for someone jaded about relationships/love it has made me pause and think about how awesome we are together..we live about 1.5 hours away from each other so we usually meet in the middle and stay at a hotel for the night....he is divorced with 2 little girls and has a great job where he is very busy (travels alot ect)....ok so everything has been wonderful until tonight when im getting ready to leave to meet him..he asked if i would mind driving down to see him to which of course i said no problem,,.i was assuming i would be going to his house but when i asked for his address he said no we were going to a hotel because his mom was there watching his 2 girls...ummmm ok well i asked him that i thought his mom lived out of town to which he replied she was visiting to take care of his girls while he is at a conference this weekend...hmmmmm does this seem weird to anyone?? why is his ex not watching his kids (who they are suppose to live with) it just seems funny..something seems off...and now that i have been thinking about it all i rememebr when we first started seeing each other i asked what his address was so i could see how far away we were from each other and he laughed it off saying we werent at that point yet for him to give me his address (thought it was weird then but dismissed it) now i have my own theory but want to hear from u guys......what do u think is going on???
