Man I'm seeing and I work diff schedules and he's a single parent. Other night made plans, they fell through but he calls next morning apologized. We communicate great via phone and in person but should I assume something's up if plans continue to fall thru. I know he has other priorities but...
If he's constantly flaking, he's not all that interested OR he's poor at managing the responsibilities of parenting and dating. Neither bodes well for you.
