I appear to have been blocked by someone I enjoyed chatting with - I have no idea why other than the fact I've not been online for a couple of days. It's a shame I didn't get to explain.
Happens a lot. Some people have no manners, unfortunately. Would not kill people to leave a message saying they don't want to talk any more. Goes with the territory here, in afraid.
Unfortunately it happens sometimes. But the issue is usually with them - not you.

If there was not explanation, or nothing obvious to why you've been blocked, then it's not probably worth worrying about it. Better that you stopped contact with that person now, because you might have become too close, and later on, she/he would have done the same thing to you.
