It is not wholly the responsibility of the man to make contact with the other individual. Claire could've made more of an effort to contact you, and you gave her a few weeks in which to do so. It's not like you didn't try to do the same yourself. She also could've mentioned that she can't be reliably reached by any means other than text messages as well. Going to her house without invitation, reaching her through other individuals, and the like all seem a little excess in your case. I, like you, would have thought it safe to assume she wasn't as interested in a dating relationship as I was, had I been you.

An adult's sex life is nobody else's concern unless they are in a committed relationship with said adult. You were in the clear in having some consensual fun with a friend, especially since you had no reason to assume "Claire" had any further interest in you anyway. Just because Claire and her friends aren't as mature about sex as you, doesn't mean you should feel guilty. You can't please them all, as they say, so move on and find pleasure elsewhere.
