What should I do after a break up with my bf? ?

So I was feeling it since December that my now ex was drawing back. We were joking and I sent him gay memes and from there some negative discussions got opened that revealed our total opposite points of view in life. I don't think I'm totally refusing of his way of thinking its just that I love arguing and get it my way even if I sometimes use arguments I myself don't believe. So the apple of the fight was now that I'm homophobic. I was raised in a religious conservatory environment and I don't approve of the gay lifestyle but that would never get into the way of me getting violent or anything. I'm just put off my these people and am scared of their way of perceiving life. So my fb told me he had withdrawn from me as he felt such energy that didn't have place in his world. And then I told I was going to make thing easier for him by unfriemding him. Thing is he lives on another state and I was supposed to go visit him, have the ticket already. I know that I'm wrong it's just that I don't think I see a future as I have different planes so I choose arguments that's start a debate and always attack. I know I'm a horrible person. Thing is I really like him as a package he's a great guy. I wish I wouldn't lose him as a friend. What would you suggest?
