The person may miss you. May miss you, appreciate you more and adjust. Might be in the near future or the far future. All relationships ebb and flow and it might be that this is a low point and things improve.
I stop if I'm starting to feel resentful, too - that point varies depending on the person.
As someone who makes and keeps friends easily, if I turn down an invitation from someone I'd like to see again (friend or developing friend), I always suggest another time. I'm clear with people I like that I enjoy their company and am willing to make the effort to maintain the friendship. I'm not friends with people who can't or won't do that (or are just not that into me as a friend, also fine).
