I'm happy you're out with this, I'm glad the charade is over with and everybody can start to heal, hopefully.
But I'm not going to give you sympathy like a lot of people here, maybe they're better than me for it, maybe they're not. I can't understand how you can wrap yourself in so many other's lives, to start relationships with people that you know you cannot keep up because somebody's eventually going to find you out. Whether they have their heart broken when they meet you for the first time, or if your avoidance of them finally tips them off and they discover you for what you are. I'd call you courageous for coming out with this if you weren't practically forced to. You didn't have to apologize, of course, so good job with that, but the fact that a lot of people are so accepting of this kind of behaviour is why it, in my opinion, is allowed to happen so frequently.
This kind of thing isn't something you just "get over," knowing that someone who was so close to you wasn't even being honest about the most basic of things like this can really put your entire relationship with them in a different light. If someone can't be honest about themselves, what should make you believe they were honest about anything else? Right or wrong, trust issues last lifetimes because of situations like this. Anyone telling people to "just get over it" are nothing but beyond disrespectful.
Don't get me wrong, though. I don't hate you for this, almost everyone deserves forgiveness in time as long as they earn it. I sincerely hope that you can.
