Is it an immature act to unfriend an EX from ur Facebook?

[Paris]

After two weeks ignoring my txts, msges and calls, he finally got back to me saying we cant be together much longer because he thinks it's for best. He didnt even give me any explanation why he thinks so.. I felt so devastated knowing that I have done noting but always supporting him, being there for him and respect him. The way he treated me by ignoring my txtxs and calls was absolutely unacceptable. I am a kind of woman who always respect everyone and i expect the same from them. But in this case after year being close together leaving in a limbo with no explanation destroyed my feelings and self-steem...im still feeling very hurt but don't want to overreact either.

He still has me on his facebook and we have a lot of mutual friends who dont know we have broken up. But im not sure if i should remove him on fb or just ignore him and let him see that Im over him and happy with my life?( even though im not but i dont ant to give him the satisfaction that im still thinking about him )...Im very hurt...NEED YOU HELP PLEASE
