<human>: Starting casually dating this guy a few months ago.

He seemed really excited about me and making plans with each other was something we both did consistently, maybe a few times a week.  At one point he went out of town and he made an effort to see me a few times up to his leaving.  When I met his best friend, he told me that guy likes me a lot and is not a big "dater"--just doesn't find women he's interested in very often. 

In the last few weeks, I've been the one to initiate, and half the time he cannot make it for one reason or another--it makes me feel blown off.  Now, when we do see each other everything is great and I feel like he genuinely enjoys seeing me.  However, it's getting further and fewer in between.  The next time I see him (assuming there is one), I kind of want to call out this behavior and just ask what his intentions are.  If he's just losing interest, I just want to know.  In the interim, I feel like I'm being strung along.  In any relationship, I've always been the giver and maybe to a fault.  Making the first move and putting in effort is not anything I am uncomfortable doing, but it needs to be a mutual thing.

Can you give me a shortened version of the text?
<bot>: Guy seemed really interested at first but isn't making the effort to make plans anymore.  Do I ask what's up, keep putting in the effort, or just don't reach out anymore?
