After months of fickleness and going back & forth of trying to maintain & reconcile for some sort of relationship post-breakup, my ex has told me that he basically doesn't want us to talk anymore, check in, or be friends. So I've stayed my distance and blocked him from everything and he has blocked me from social media. However, after weeks of contact I got into a moment of weakness out of temptation & curiosity to check his sister's FB page as it is public and we've had a pretty cool relationship. A few hours later I received a notification saying that his sister accepted my friend request. Somehow I have managed to successfully accidentally request her and now we're friends on Facebook. This happened 3 days ago. What should I do, if at all anything at this point?
