"I don't see why not" meaning?

We've been communicating for about five months...we tried meeting twice, but one of us was busy.

I shot him this the other day...

Me: I know/understand that your busy w farmin, work, school & chillin w your family/buds All I want is 5 min if you don't want to I completely understand But just tell me! No more hee-hawin around! I'm sensitive, but I can handle being shot down. I don't want this to ruin our friendship but I wanna knw so I stop buggin ya

Him: I don't see why not!

I don't understand why he'd say that...why can't he just be honest with me and say no!
