The dude must realise the following:
It is his decision if he likes you.
However it is not his decision if he is enough for you. It is also not his decision wether you like him or love him or dislike him.
He therefore cannot and should not make decision based on what he is thinking that you are thinking (thats stupid!).
Maybe he is prejudiced to the whole skype/long distance thing. Many people have the believe that such relationships simply cant work out (which is wrong, as I have proven personally).
Maybe he is missing physical contact. Maybe he doesnt like himself.
However all of the above are stupid reasons not to do your very best to be with someone you like.
If he doesnt like you - thats another matter entirely.
But if he does and there are no other reasons on HIS side, then it should not be his decision to end a relationship.
He can vocie his doubts - ok. However if you tell him seriously (and are honest with it) that you want all of the things he is unsure about, then it is your decision.
I can relate because it is a matter of not liking yourself enough to believe that other people can like you with all your errors and wanna be with you.
And accepting that and additionally accepting and liking yourself is difficult for some people. Mostly to those people who are actually reflecting themselves and therefor are usually decent persons. But that is getting us carried away here.
If you think I am insulting you with my post or bashing you: You do not get the point.
I am not here to insult or bash anyone. I offer up my free time to help. Take from my post what is useful to you.
If you are angry about my post or myself, then please stop and think how that happened. Usually that is the way the brain responds if a critical belief system is challenged (its called cognitive dissonance). If you have trouble with it please answer in the thread. I will come back to you.
