We're not sure you can have a relationship when you haven't actually met the person. Three years is quite a long time – has he ever asked to meet you, and have you asked to meet him? Even though you have been talking for three years – it is very easy to hide from someone, and tell lies about yourself online. You never actually know who you are talking to and it could become dangerous and unsafe. Unfortunately there are many people out there who just want to take advantage of innocent, unassuming people. Remember be on your guard, the internet is tricky – and if you do eventually meet this guy take someone with you.
